基于矿山工程地质特点的岩爆防治措施研究

Study on rock burst prevention measures based on mine engineering geological characteristics

为了能够满足人们日益增长的矿产资源需求,矿山开采的规模越来越大,在矿山开采的时候经常会遇到地质条件比较复杂的区域。同时,在开采的时候,由于开采深度的逐渐增加,容易遇到一些高地应力和断层比较复杂的地质环境,除此之外,深部的岩体由于在地下高地应力的作用下进行开挖扰动的时候,围岩应力会受开挖扰动的影响进行重新的分布。由于开采深度的逐渐增加,导致采空区暴露的面积逐渐的增加,受到开挖卸荷以及复杂地质构造的影响,容易使得比较坚硬的岩石出现岩爆的问题,给井下的开采环境带来极大的破坏,威胁井下作业的顺利开采,给施工人员的生命安全带来极大的威胁,造成巨大的经济损失。导致岩爆发生的原因是多种多样的,主要原因便是矿山工程地质的特点影响。面对发生的矿山岩爆问题,需要采取有效的矿山安全管理措施对矿山岩爆进行有效的防护,以此保证矿山开采的顺利进行。本文便首先讲述矿山岩爆现象的分析,其次讲述矿山岩爆的影响,最后讲述基于矿山工程地质特点岩爆防治具体措施,以此来供相关人士参考与交流。

In order to meet people's increasing demand for mineral resources,the scale of mining is becoming larger and larger.When mining,the geological conditions are often more complex.At the same time,during mining,due to the gradual increase of mining depth,it is easy to encounter some geological environments with high ground stress and relatively complex faults.In addition,when the deep rock mass is disturbed by excavation under the action of high underground ground stress,the surrounding rock stress will be redistributed under the influence of excavation disturbance.Due to the increase of mining depth and the area of the mined-out area exposed gradually increased,under the influence of excavation unloading,and complex geological structure,easy to make more hard rock rock burst problems,to the underground mining environment brings great damage,threat smooth mining of underground work,the life safety of the construction personnel to bring huge threat,cause huge economic losses.The reasons leading to rockburst are various,the main reason is the characteristics of mine engineering geology.In the face of rock burst in mines,it is necessary to take effective safety management measures to protect rock burst in mines,so as to ensure the smooth progress of mining.This paper first describes the analysis of mine rockburst phenomenon,then describes the impact of mine rockburst,finally describes based on the characteristics of mine engineering geology rockburst prevention measures,so as to provide reference and communication for the relevant people.
