在金属矿山中,开采过程对近矿体巷道的影响规律极为重要,在深部,这个问题更为突出。本文介绍从险区调查获得的地压活动规律和距地表千米深处巷道围岩位移长期监测的结果。在现场工作的基础上进行了模拟研究与相应的分析工作。
In metal mines, the influence of the mining process on the roadway near the ore body is extremely important. In the deep area, this problem is more prominent. This article introduces the law of underground pressure obtained from the survey of dangerous areas and the result of long-term monitoring on the displacement of surrounding rock in tunnels at a depth of kilometers from the earth’s surface. On the basis of field work, the simulation research and the corresponding analysis work were carried out.
