摘要

目的。在大型矿床开发过程中,对矿坑内部采空区及其各剖面充填覆岩是合理利用矿坑周围土地的主要措施。挖掘、移动和储存覆岩以及开采矿物的资金费用大大减少。在深坑采空区储存覆岩,减少了覆岩的运输距离,节省了大量的土地面积,使其免受外部排土场的干扰。众所周知,一组矿床或大型矿坑的开采应伴随着第一阶段的矿坑分配,将其开采到极限轮廓,随后进行采矿作业,并在空空间中分配队列和储存覆盖岩。的方法。根据所提出的技术方案,确定了在深坑开发过程中,将工作面覆岩移至内部堆积场并进行后续储存的程序和方法。利用现代GIS技术和K-mine软件进行计算。在计算内部排土场覆盖层体积时,采用了垂直线剖面法。发现。当开采一个深坑时,由于运输通信的正确放置和内部堆积场的形成,从较低水平运输覆盖岩层的距离减少了。矿床开发队列的分配使得有可能在采矿前沿的后续推进中形成第一阶段的坑,并确定要放置在内部排土场的岩石体积。的创意。进行了分析,并确定了创建内部转储的顺序和方法。在不考虑和不考虑岩石松动系数的情况下,建立了堆积场形成各阶段所储存的上覆岩体积的图形依赖关系。实际implimintation。在Poltava矿坑的空地区域内,可以放置大量的覆岩,这对环境和企业的经济效益都有积极的影响。

Stages of creating an internal dump in a deep pit
Purpose. Filling with overburden rocks of the internal mined-out space of the pit and its individual sections is the main measure that contributes to the rational use of land around the pit in the development of deposits of significant size. There is a significant reduction in the cost of funds for the exca-vation, movement and storage of overburden rocks, as well as the extraction of minerals. Storage of overburden rocks in the mined-out area of deep pits reduces the distance of their transportation, saves significant land areas from disturbance by external dumps. It is known that the exploitation of a group of deposits or pit fields of significant size should be accompanied by the allocation of a pit of the first stage, mining it to the limiting contours and subsequent advancement of mining operations with the allocation of queues and storage of overburden rocks in the empty space. The methods. The procedure and methods for moving overburden rocks from the face to internal dumps with their subsequent storage during the development of deep pits according to the proposed technological scheme are determined. The calculations were performed using modern GIS technolo-gies using the K-mine software. To calculate the volume of overburden, which is placed in internal dumps, the method of vertical sections is applied. Findings. When mining a deep pit, the reduction in the distances for transporting overburden rocks from the lower levels is achieved due to the correct placement of transport communications and the formation of internal dumps. The allocation of development queues at the deposit makes it possible to form a pit of the first stage with the subsequent advancement of the mining front and determine the volume of rocks to be placed in the internal dump. The originality. The analysis was carried out and the sequence and methods for creating internal dumps were determined. The graphic dependences of the volumes of overburden rocks stored at each stage of the formation of dumps are established, without taking into account and taking into account the coefficient of loosening of the rocks. Practical implimintation. Within the empty space area of the Poltava Mining pit, it is possible to place significant volumes of overburden rocks, which will positively affect both the environment and the economic performance of the enterprise.
