Roadheaders are extensively utilized for tunnel heading rock engineering applications all over the world. To create a work plan and calculate costs, it is critical to forecast roadheader performance as precisely as possible. Machine utilization time (MUT) is required for the calculation of daily advance rate of roadheaders. This paper investigates the values of MUT for roadheaders used in underground coal mines. The performance measurements were conducted on fifty different locations for axial machines and thirty-nine different locations for transverse machines. MUT values vary from 15 % to 37.5 % with an average of 26.3 % for axial roadheaders, and vary from 6.9 % to 37.9 % with an average of 18.4 % for transvers roadheaders. The average MUT is 25.4% for all measurements. The percentage of average support time approximately equals to the average MUT. Multiple regression and artificial neural network models were also developed for estimating MUT. Concluding remark is that the determined MUT values and the derived estimation models for roadheaders will be very useful for coal miners.

In order to solve the problem of dust pollution in open-pit coal mine, this paper studies the characteristics and prevention measures of dust pollution in open-pit coal mine. Firstly, the effects of different phosphorus treatments on pH value and water-soluble phosphorus of dust polluted soil in open-pit coal mine, the effects of different phosphorus treatments on water-soluble lead and zinc, and the effects of different phosphorus treatments on the contents of exchangeable lead and zinc in dust polluted soil were analyzed. On this basis, multi-directional dust pollution control measures with public participation in construction dust supervision and control as the core are put forward. The test results show that after comprehensive treatment, the amount of dust is reduced, and the phosphorus containing substances can repair the polluted soil of open-pit coal mine, and a good soil remediation effect is achieved.

In this work, the use of water (W) as a grinding additive in addition to waste/by-products such as olive black water (BW) and residue of olive black water (RBW) in calcite dry grinding to be sized in microns was investigated at a laboratory scale. The test results were evaluated based on product fineness, grinding time, liquid material dosage, and powder flowability. The study revealed that the use of any kind of liquid materials tested improved the grinding process compared to the blank condition. Considering RBW, powder flowability increased as its concentration increased. The findings from both the BW and W data revealed that the dose increase does not yield favorable outcomes in relation to the ffp index. Nevertheless, there was a noticeable enhancement in particle fineness.

Friction anchor bolts are commonly used for providing support in underground structures by relying on frictional forces between the bolt and the surrounding rock. This study proposes a method to enhance the efficiency of these bolts by injecting a cement-based mixture comprising cement, sand, and additives. The injection of this mixture into the bolt results in internal expansion, which reinforces the friction and bearing capacity of the bolt. The increased volume exerts a radial force, leading to improved adherence, load transfer, and void filling. Pullout tests were conducted on various rock masses to evaluate the performance of the anchor bolts. The results demonstrate increased pullout resistance with higher rock mass quality and longer cemented bolts. Additionally, the use of a silicate-based additive accelerated the curing time of the cement, enhancing the strength of the bolts. The study also highlights the significant influence of groundwater on the bearing capacity of the bolts. These findings indicate the effectiveness of cemented concrete injection in strengthening friction anchor bolts and their anchorage in underground structures.

Support pressure is a key factor in the stability of the excavation area during mining and tunneling. The vital thing desired in an underground engineering structure is to ensure that the structure survives safely throughout its lifetime. For this reason, choosing the right support system at the planning stage is very important for the pressure that will affect the support system must be determined with a certain convergence. This article aims to discuss the support pressures by the finite element method and convergence-confinement method and compare the results. A series of two-dimensional finite element models are established to analyze support pressure with different rock masses selected from the literature. The results reveal that since the convergence-confinement method and the finite element method have high-order relationships regarding support pressures and displacements for weak rock masses, the support pressures and the displacement values for similar conditions can be estimated with the convergence-confinement method, which is more practical than the finite element method.

Due to low production cost, coal is still the most important source of electricity production worldwide. This important position of coal also makes the evaluation of coal resources important. One of the most important attributes to be assessed in this evaluation is estimating the calorific value distribution of deposit. In geostatistical estimation currently Kriging and its variants are being used widely. Alternatively new techniques are being developed and one of them is the Radial Based Functions based method. In this study, Conditioned Radial Basis Function (CRBF) is used to estimate the calorific value distribution of a coal deposit while estimations are also performed with Ordinary Kriging (OK). Results of both estimation methods are compared with respect to composite calorific values. Results show that CRBF produced a higher estimation range than OK with closer mean to composite. However, like OK, results are still smoother than the composite values.

To solve the problem of floor water inrush in the process of coal mining on a confined aquifer and study the law of floor instability, a cemented filling mining method is proposed in the paper. Using river sand and cement as filling materials, the cementitious material with a concentration of 75% and cement content of 15% has the best flow and mechanical properties. Based on the elastic half-space theory and the bearing characteristics of the backfill, the mechanical model of floor stability is established, the critical criterion of floor instability is proposed, and the relationship between the failure depth of floor and the location and pressure of confined aquifer is obtained. The numerical simulation test scheme is designed, and the FLAC3D fluid-structure coupling element is used to explore the instability characteristics of the floor in the mining process. The research results show that the failure depth of the floor will gradually decrease with the increase of the strength of filling materials, the increase of aquifer distance, and the decrease of water pressure. The research results provide a useful reference for the study of safe mining of coal resources on a confined aquifer.

To study the significance of different factors on adjacent underground laminated salt rock storage, 15 groups of simulation tests are designed by using the response surface methodology (RSM), the quadratic response surface model with the midpoint displacement and medial waist stress of the interlayer as the response values is constructed. By analyzing the main effect and interaction of the regression model, the influence of the interaction between pillar width, interlayer thickness, and the location of a single interlayer on the midpoint displacement of the interlayer and the internal waist stress of the adjacent ellipsoidal cavity is studied. The results show that the interlayer thickness is the main effect factor of the midpoint displacement of the interlayer. And the pillar width is the main effect factor of the medial waist stress. When the adjacent storage is designed with as 2.5D pillar width, 2 m interlayer thickness, and the midpoint of the interlayer is located at 0.3H above the cavity, the displacement and stress of the test model are relatively small. The above conclusions can provide a certain reference value for the mechanical analysis of adjacent underground layered salt rock gas storage.

The traditional way of coal production and management is still predominant in the Indian coal mining industry which has led to a widespread waste of resources both materials and humans. Operational loss of the mining machinery and equipment is one of the key factors for the low performance and productivity of mines. This research presents an application of the integrated approach of the Mine Production Index and Ishikawa Diagram in an Indian coal mine to study the bottleneck equipment in the mining operation among the fleet of the shovel, dumper, and dozer. Mine Production Index (MPI) identifies the bottleneck equipment in the mining operation, and Ishikawa Diagram presents the Root Cause Analysis of bottleneck equipment. The fuzzy Analytic Hierarchy Process (FAHP) is used to determine weights for MPI calculation using information gathered from a group of 11 experts through Structured interviews. The study found that the dozer fleet is the bottleneck equipment and the ineffectiveness of the dozer fleet can be grouped into 4 categories as enumerated on the Ishikawa diagram. The study proposes that the ineffectiveness of the dozer fleet can be improved with an increase in its performance rate. The study is based on the judgments of the experts for the case mine, which may limit the external validity. This paper is an original contribution to the analysis of mining equipment using the Mine Production Index and Ishikawa Diagram in an Indian coal mine.

Glycerin represents the primary by-product of biodiesel generation when vegetable oil is transesterified with ethanol or methanol. Nowadays, the need to turn to alternative materials is increasing due to the competition arising from developing technology and industry and the rapid consumption of Earth’s resources. It is essential to study how to prevent the depletion of natural resources and transform wastes into usable and valuable products. The use of waste glycerin (WG) as a grinding aid can constitute an alternative solution in terms of utilizing the excess glycerin resulting from biodiesel production. This paper investigated the usability of WG as a grinding aid in terms of grinding efficiency while planning to decrease the adverse impacts of waste on the environment via its efficient utilization. The dry grinding experiments conducted within the study’s scope researched the impacts of five biodiesel dosages (0%, 0.25%, 0.5%, 1%, and 2% by weight) on the product. The current research is promising in terms of preventing the depletion of natural resources and transforming waste into usable and valuable products. Furthermore, considerable enhancements were obtained in the grinding performance with the grinding aid utilized.
