大平煤业井下巷道降低冲击地压方案的研究

Study on Scheme of Reducing Rock Burst in Underground Roadway of Daping Coal Industry

为解决山西大平煤业有限公司7712综采面地质条件复杂,频繁出现巷道垮塌、围岩垮落的异常,本文针对性地提出了冲击地压预警监测系统、大直径钻孔泄压及打孔爆破泄压控制方案。目前该方案已在大平煤业全面推广,取得了极好的应用效果。

In order to solve the complex geological conditions,the anomaly of roadway collapse and surrounding rock collapse frequently occurs of the 7712 fully mechanized mining face of Shanxi Daping Coal Industry,this paper puts forward the impact ground pressure early warning monitoring system,large diameter borehole pressure relief and drilling blasting pressure relief control scheme.At present,the scheme has been popularized in Daping Coal Industry,and has achieved excellent application results.
