Abstract

Maintaining and increasing the volume of underground coal mining is possible only if there is a highly efficient technology for conducting and maintaining preparatory workings. The purpose of the research was to assess the parameters of stability control of the contours of the mine workings, anchored with anchorage, to create a technology for intensive and safe excavation of mine workings based on the identified patterns of behavior of adjacent rock massifs. The idea of the approach is to use a man-made stress-strain state to develop an effective technology for fixing a contour rock mass. The mechanism of deformation, displacement, and collapse of rocks in a structurally disturbed inhomogeneous mountain range is investigated to assess the state of the rock mass around the mine workings. The technology of fastening contiguous soil rocks has been developed taking into account the state of the mountain massif around the workings and the parameters of the operation of the anchor supports in mines for fixing rods in workings in order to ensure the safety of mining operations in the mines of the Karaganda coal basin have been determined.
准备工作期间的应力应变状态监测
只有在有进行和维持准备工作的高效率技术的情况下,才有可能维持和增加地下煤矿的开采量。该研究的目的是评估用锚固锚定的矿山工作轮廓的稳定性控制参数,以创建一种基于确定的相邻岩体行为模式的矿山工作密集和安全开挖技术。该方法的思想是利用人造应力-应变状态来开发一种有效的固定等高岩体的技术。研究了结构扰动下非均质山区岩石的变形、位移和崩塌机制,以评估矿区周围岩体的状态。为保证卡拉干达煤田煤矿的安全开采,在考虑矿区周围山体状况的情况下,开发了连续土岩锚固技术,并确定了矿山锚杆支护的作业参数。
