摘要
本文综合分析了锡矿山北矿童家院矿床岩石移动、岩体声发射和光应力计观测结果，通过和以往南矿大面积地压发生和发展过程中地压监测结果的对比分析，指出童家院矿床三中段１２７～１９３采场目前处在大面积地压预兆期，并提出应采取的地压控制措施。
Abstract The paper analyses comprehensively the observation results of the rock displacemeter gauge,rock body' sound emission meter and optical stress gauge for Tongjiaguan deposit of the North Mine in Xikuangshan. Through the comparative analysis with the inspection results during the occurrence and development of the large-area ground pressure in the South Mine,the paper points out that the 127～193 stope of the third middle section in Tongjiaguan deposit is now in the signs period of the large-area ground pressure and makes the suggestions on the measures that should be taken to control the ground pressure.
