Description
技术领域 technical field

背景技术 Background technique
冲击地压是指在煤矿井巷或回采工作面周围,处于高地应力条件下的煤岩体受到顶板断裂或爆破扰动发生破坏,并在破坏过程中受到围岩的进一步快速挤压作用,瞬时释放巨大能量而产生破坏的矿井动力现象。常伴随有巨大的声响、煤岩体被抛向采掘空间和气浪等现象,造成采掘空间中支护设备的破坏以及采掘空间的变形,严重时造成人员伤亡和井巷的毁坏,甚至引起地表塌陷而造成局部地震。 Rockburst refers to the fact that the coal rock mass under high ground stress is damaged by the roof fracture or blasting disturbance around the coal mine roadway or mining face, and is further and rapidly squeezed by the surrounding rock during the destruction process, and is released instantaneously. A mine dynamic phenomenon in which huge energy causes destruction. It is often accompanied by loud noises, coal and rock mass being thrown into the mining space and air waves, etc., causing damage to the support equipment in the mining space and deformation of the mining space, causing casualties and damage to the mine and roadway in severe cases, and even causing surface subsidence cause local earthquakes.
冲击地压是采矿业面临的一个重要问题,严重影响着矿井的安全生产,尤其是在深部开采过程中,围岩处于高应力条件下,受到采场上覆岩层断裂扰动,回采巷道很容易发生冲击地压灾害。研究冲击地压发生规律,不仅要通过理论分析,更要通过室内模拟实验来探索其本质规律。 Rock burst is an important problem faced by the mining industry, which seriously affects the safe production of mines. Especially in the process of deep mining, the surrounding rock is under high stress conditions, and is disturbed by the fracture of the overlying strata in the stope, and the mining roadway is prone to occurrence Rockburst disaster. To study the occurrence law of rock burst, it is necessary not only to conduct theoretical analysis, but also to explore its essential law through indoor simulation experiments.
根据现场观测和理论分析认为,为了在室内模拟冲击地压现象,需满足如下三个必要条件: 通过加载,使煤岩体处于高应力状态下;对高应力条件下的煤岩体施加冲击荷载,以模拟采空区覆岩断裂导致的应力波对巷道的冲击;在煤岩体破坏的过程中迅速进行补充加载,即补充能量,以模拟外部围岩对煤岩体的进一步挤压做功。但是,目前还没有设备能够同时满足上述三个条件,实验室模拟成为冲击地压的研究的瓶颈。 According to field observations and theoretical analysis, in order to simulate rock burst indoors, the following three necessary conditions must be met: By loading, the coal and rock mass is placed in a state of high stress; The impact load is applied to the coal and rock mass under high stress conditions to simulate the impact of the stress wave on the roadway caused by the fracture of the overlying rock in the goaf; In the process of coal rock mass failure, supplementary loading is carried out quickly, that is, energy is added to simulate the further extrusion work of the external surrounding rock on the coal rock mass. However, there is no equipment that can meet the above three conditions at the same time, and laboratory simulation has become the bottleneck of rock burst research.
