大倾角条件下综采工作面过断层回采实践

综采工作面遇断层时,极容易出现片帮、冒顶等顶板事故,尤其是在落差大于采高、大倾角工作面等困难条件下,给安全生产带来巨大的压力和困难,葛泉矿通过长短距离注浆加固、严格的回采工艺措施,实现了大倾角条件下综采工作面顺利通过大落差断层,避免了工作面搬家,杜绝了顶板事故,取得了宝贵的现场经验。

The practice of fully-mechanized coal mining for belt of fault in steeply dipping seam

In fully mechanized working, the faul is very prone to cause spalling and roof falling accident, especially in the qualita- tive difference of fault and steeply dipping seam , the more difficult conditions bring great pressure and more difficulties to the safety production, gequan coal mine, through long and short range of chemical grouting and strengthening measures of fully - mechanized coal mining technology , realizing the Safety mining and passing the belt of fault successful, avoiding the Fully mecha- nized moving and roof accidents, acquiring the precious experience and practice.
