冲击地压是矿山压力的最危险的显现形式之一。冲击地压会给生产过程造成严重的破坏,会使地下构筑物遭受破坏。掘进巷道时的重要任务是查明岩体的冲击地压危险性,以便及时采取预防措施。岩体冲击地压的危险状态受采矿技术和地质因素的影响。巷道掘进本身应当首先认为是采矿技术因素,巷道造成在岩体中出现暴露面。这一因素的重要性是很明显的,因为不存在空区和结构破坏时,岩体则处在全面压缩条件下,类似于未扰动的静水介质,此时冲击地压的概念失去了意义。由重力和地质构造力所造成的岩体应力,巷道断面形 Rock burst is one of the most dangerous manifestations of mine pressure. Rockburst can cause serious damage to the manufacturing process and damage to underground structures. The important task when driving a roadway is to find out the rock burst risk, in order to take timely preventive measures. Rock burst pressure of the dangerous state of mining technology and geological factors. Roadway boring itself should first be considered as a mining technology and the roadway causes an exposed surface in the rock mass. The importance of this factor is obvious because in the absence of empty zones and structural failure, the rock mass is under full compression, similar to undisturbed hydrostatic media, at which point the concept of rockburst lacks meaning. Rock mass stress caused by gravity and geological tectonic force, roadway profile
