摘要： 为解决红阳三矿7 号煤层构造区域综采工作面的冲击地压防治问题，以西三采区703 工作面开切眼处断层带
卸压为工程背景，以深孔预裂爆破的卸压方式，基于钻孔窥视技术对其深孔卸压爆破的有效性进行分析，检验所采取措
施的有效性。结果表明，深孔爆破卸压方式对于断层带等应力集中区域卸压效果良好，采用卸压爆破的手段后，该区域
的冲击危险程度降低，为深部构造区域工作面的安全回采奠定了基础。

Abstract: In order to solve the problem of rockburst prevention in fully mechanized mining face in structural area of No.7 coal
seam of Hongyang No.3 Coal Mine, taking the pressure relief of the fault zone at the open-off cut of the 703 working face in the
west No.3 mining area as the engineering background, this paper analyzed the effectiveness of the deep hole pre-splitting blasting
of deep hole pressure relief blasting based on the drilling peeping technology to test the effectiveness of the measures taken. The
results showed that the pressure relief method of deep hole blasting had a good pressure relief effect on stress concentration areas
such as fault zones, and after adopting the pressure relief blasting method, the impact risk in the area was reduced, which laid a
foundation for the safe mining of working faces in deep structural areas.

Key words: drilling peeping technology; deep hole pre-splitting blasting; blasting pressure relief; effectiveness of pressure relief
