回风顺槽沿顶掘进在贵石沟矿井综放工作面的应用

Application of Return Airway Excavating along Roof of Fully-Mechanized Top Coal Caving Face in Guishigou Coal Mine

结合贵石沟矿井8407工作面的具体地质条件,提出了8407综放工作面回风顺槽沿顶掘进的方式,并分析了工作面回采期间矿压显现情况。结果表明,综放工作面回风顺槽沿顶掘进能够较好地解决沿底掘进存在的问题,实现安全高效生产,具有较良好的可行性。

Combines with Guishigou mine 8407 working face specific geological condition,return airway excavating along the roof of 8407 fully mechanized top coal caving face is proposed, and the conditions of mine pressure appearance are analysed. Results show that return airway excavating along the roof of fully-mechanized top coal caving face can solve the problems better on excavating along the bottom. It can achieve safe and efficient production and has relatively favourable feasibility.
