综采工作面穿层回采技术研究与实践

Study and Practice of Stoping Technique Across Coal Strata for Fully Mechanized Mining Face

针对宜兴煤业公司1206综采工作面材运两巷错层段的具体情况,对在复杂地质条件下,材运两巷在2#煤层不同分层、工作面穿层回采,提出了现场技术指导和施工方案,降低了地质和人为因素的影响,通过采取合理有效的安全措施和施工工艺、加强生产组织管理,保证了工作面的安全生产,提高了回采效率,取得了显著的经济和社会效益,对在复杂条件下综采生产提供了实践经验。

According to the specific situation of stagger section layer of timber roadway and transport roadway in Yixing coal industry 1206 fully mechanized mining face,in complex geological conditions,the two roadways were arranged in different layers of 2# coal seam and working face stoping across coal strata,the site technical guidance and construction scheme were put forward to reduce the impact of geological and human factors.By taking reasonable and effective safety measures and construction techniques,and strengthening production organization and management,the safety of working face production was ensured,and the recovery efficiency was improved,and remarkable economic and social benefits had been achieved.It provided practical experience for fully mechanized mining under complex conditions.
