摘要
为了保证巷道掘进施工安全,防止巷道掘进期间受地质条件影响造成顶板冒落、煤壁片帮等重大煤矿安全事故,回坡底煤矿通过技术研究,对1121系统巷前期掘进过断层破碎带期间采取了合理有效的安全掘进技术措施,通过实际应用效果来看,采取安全技术措施后,巷道在过断层破碎区期间未发生顶板事故,保证了巷道安全快速掘进。
In order to ensure the safety of roadway excavation and prevent major coal mine safety accidents caused by geological conditions during roadway excavation,through technical research,reasonable and effective safety tunneling technical measures have been taken during the early excavation of 1121 system roadway over fault break zone.After adopting safety technical measures,the roadway does not have roof accidents during fault breaking area,which ensures the safety and rapid tunneling of roadway.
