目前,采矿工程大部分都需要采用凿岩爆破方法完成。因而矿井巷道围岩频繁地承受着重复振动的冲击动载荷作用,其结果产生了动应力,当这种动应力大于岩石强度时,围岩被破坏失去稳定性产生地压。本文就爆破与地压的关系,以及在不影响爆破效果的前提下,探讨如何最大限度地减小爆破引起 At present, most of the mining engineering needs to be completed by the rock drilling method. As a result, the surrounding rock of mine roadway frequently undergoes the impact dynamic impact of repeated vibration. As a result, dynamic stress is generated. When the dynamic stress is greater than the rock strength, the surrounding rock is destroyed and the stability is lost and the ground pressure is generated. In this paper, the relationship between blasting and ground pressure, and without affecting the blasting effect under the premise of how to minimize blasting caused
