摘要
断层在井工煤矿采掘时极为常见,采掘工作遇断层时必须制定针对性安全技术措施。以汾西矿业集团南关煤业公司3205工作面过F7断层为工程背景,综合运用现场调研、理论分析及文献查阅等研究方法,对工作面过F7断层的工程难点进行分析,进而设计了工作面调斜及层位调整的推采工艺,以及过断层期间的顶板注浆加固方案及管理措施,并成功进行了工程实践,实现了预期的安全及技术目的。
Faults are very common in mining of underground coal mines.When mining meets faults,targeted safety technical measures must be formulated.Taking the 3205 working face of Fenxi Mining Group Nanguan Coal Industry Company passing through F7 fault as the engineering background,the engineering difficulties of working face passing through F7 fault are analyzed by comprehensively using the research methods of on-site investigation,theoretical analysis and literature review,and then the push mining technology of working face inclination adjustment and horizon adjustment,as well as the roof grouting reinforcement scheme and management measures during passing through the fault are designed,and the engineering practice is carried out successfully.The expected safety and technical objectives have been achieved.
