摘要

目的。工业矿物开采技术论证采用移动式破碎筛选厂。方法。对采石场进行了分析、统计、图分析和实验研究。发现。通过研究,确定了移动设备开采混杂岩技术对采掘、装载和运输设备能力的影响。以奥达里夫斯基杂岩矿床为例,利用移动设备对工业矿物开采工艺因素的复杂影响进行了研究,得出以下结论:使用位于采石场的移动式破碎和筛选设备,可以使装载破碎机料斗的挖掘机的生产率比装载在拖车中的生产率提高16.7%,与破碎和筛选设备位于地面的循环技术相比,使拖车的生产率平均提高25%,拖车从采石场运输原材料。矿山运输设备生产率的提高是由于挖掘机在等待搬运车的同时没有停机时间,并且在运输高容重的成品碎石产品时最大限度地利用了车辆的载荷。独创性在于确定工业矿物开采的特点,并确定直接在采石场工作地点使用移动式破碎和筛选设备时采矿运输设备的生产率变化的依赖性。实用价值。研究的结果证明,在奥达里夫斯克混浊岩矿床使用移动式破碎和筛分设备,将原料提取循环技术的复杂机械化是合理的,这提高了提取和装载设备和搬运车的使用效率。这最终减少了对运输设备的需求,并提高了整体采矿效率,在工业矿物开采生产骨料。

The justification for using mobile crushing and screening plants in quarrying industrial minerals
Purpose. Industrial minerals mining technology justification using mobile crushing and screening plants. Methodology. Analytical, statistical, graph analytical methods and experimental research were used on working quarries. Findings. The research made it possible to establish the influence of the migmatites mining technology by mobile equipment on the capacity of the extraction-loading and transport equipment. The following conclusions can be made based on the studies of the complex influence of the factors of the industrial minerals mining technology by mobile equipment on the example of the Odarivsky deposit of migmatites. Using mobile crushing and screening equipment located in the quarry allows for increasing Excavator Productivity for loading crushers' hopper at 16.7% compared to the loading in haulers and increases the productivity of haulers at an average of 25% compared to the cyclic technology in which the crushing and screening equipment is located on the surface, and haulers carry out the transportation of raw material from the quarry. The increase in the productivity of mining transport equipment is achieved due to the absence of downtime of the excavator while waiting for haulers and the maximum use of the vehicle's load when transporting finished crushed stone products with a high bulk density. Originality consists in establishing the peculiarities of industrial minerals mining and establishing the dependences of changes in the productivity of mining transport equipment when using mobile crushing and screening equipment directly on the working sites of the quarry. Practical value. The results of the research made it possible to justify the complex mechanization of the cyclic technology of raw material extraction with the use of mobile crushing and screening equipment for the application in Odarivsk migmatite deposit, which increases the efficiency of the use of extraction and loading equipment and haulers, which ultimately reduces the need for transport equipment and improves the efficiency of the mining as a whole during the industrial minerals mining for the production of aggregates.
