摘要

目的。改进剥离技术和在深坑中制造陡沟的方案,使创造新的货物流和发展采矿作业成为可能。研究工作的目的是确定一种更有吸引力的输送机路线形成方案。本文比较了两种技术方案:用岩石的隆起在较低的地平线上创造一个陡峭的半沟和在岩石中以沟槽的形式形成一个工作。上述工作的目的是证实一个有效的方案,以创造一个陡峭的沟槽,以便随后在其基础上放置一个输送机堆栈。这样就可以以较低的成本将岩体从较低的地平线移到较高的地平线。在Poltava GOK露天开采条件下,最具吸引力的方案是在打开较低的视界时创造一个倾斜的工作,这可以减少露天开采中自卸卡车的使用。的方法。采用垂直剖面法计算了沟槽形成过程中矿井径流的体积。利用地理信息系统(GIS)和K-MINE软件包进行研究。通过比较工作范围和创建输送机路线的方法,可以确定最合适的工作方式。发现。研究了陡沟和半沟的参数,包括在PGOK露天矿西侧陡层内确定的工作范围。打开陡峭的沟槽,允许放置现有的电梯,放置破碎和中转站,其中包含来自克虏伯的移动破碎机。实施岩中陡沟方案,工程范围为7955.5万m3。半沟施工,工程量为73388.7万m3。在波尔塔瓦采矿和加工厂露天开采的条件下,建造基本壕和半壕时,优先考虑半壕,半壕是由岩石形成的(不钻孔和爆破)。的创意。考虑了为进一步在其基础上放置输送机堆栈而创建陡峭沟槽的选项和参数。改进了将岩体从较低的水平移到较高的水平的方案,建立了工作范围的图示依赖关系,并比较了建立陡沟和半沟的技术指标。实际implimintation。考虑创建一个陡峭的沟槽的方案,可以确定准备工作的数量,在Poltava GOK的活动露天矿场的条件下,建立一个最具吸引力的方案,以创建一个倾斜的工作,打开较低的视野,这使得有可能减少露天矿场内自卸卡车的使用,并改进移动岩体的方案。

Methods of creating a conveyor lift route in a deep pit
Purpose. Improving the technology of stripping and schemes for creating a steep trench in a deep pit makes it possible to create new cargo flows and develop mining operations. The purpose of the research work is to determine a more attractive scheme for the formation of the conveyor route. The paper compares two technological schemes: the creation of a steep half-trench to the lower horizons with the hilling of rocks and the formation of a working in the rocks in the form of a trench. The above purpose of the work is to substantiate an effective scheme for creating a steep trench for the subsequent placement of a conveyor stack on its base. This will allow moving the rock mass from the lower horizons to the upper ones at a lower cost. The considered schemes for creating the steep trench allowed it possible to determine the volume of preparatory work, the most attractive scheme for creating an inclined working during opening lower horizons in the conditions of the operating open pit of Poltava GOK, which makes it possible to reduce the use of dump trucks inside the open pit. The methods. The method of vertical sections was used for the calculation of the volumes of run-off-mine during the formation of the trench. A geographic information system (GIS), and a software package K-MINE was used for research. The method of comparing the scope of work and creating a conveyor route by options allowed to determine the most appropriate way of doing work. Findings. The parameters of a steep trench and half-trench were studied, including the established scope of work within the steep layers of the western side of the PGOK open pit. Opening with steep trenches allows for the placement of an existing elevator with the placement of a crushing and transfer station containing a mobile crusher from KRUPP. Implementing the scheme with a steep trench in the rocks, the scope of work is 79.555 thousand m3. For the construction of a half-trench, the amount of work is 733,887 thousand m3. Building capital trenches and semi-tranches in the conditions of the open pit of the Poltava Mining and Processing Plant, preference is given to semi-trenches, which are created from rocks (without drilling and blasting). The originality. The options and parameters for creating steep trenches for further placement of a conveyor stack on its base are considered. The scheme for moving the rock mass from the lower horizons to the upper ones has been improved, graphical dependencies of the scope of work have been established, and a comparison of technical indicators has been made for creating a steep trench and a half-trench. Practical implimintation. The considered schemes for creating a steep trench allowed to determine the volume of preparatory work, to establish the most attractive scheme for the creation of an inclined work in opening the lower horizons in the conditions of the active open pit of the Poltava GOK, what makes it possible to reduce the use of dump trucks inside the open pit and improve the schemes for moving rock mass.
