突出危险采煤工作面综合防突技术

阳泉煤业集团有限责任公司新景矿3#煤层属于煤与瓦斯突出煤层,采用工作面放震动炮、落煤炮等诱导煤与瓦斯突出措施,既不安全,又严重影响了回采工作面生产效率。通过采用工作面应力衰减段实施浅孔注水水力挤出,以及工作面进风巷打本煤层预抽瓦斯钻孔,在应力峰值段实施瓦斯抽放的综合防突技术,较好地消除了工作面突出危险性,提高了单产,实现了安全回采。

Outstanding Danger Adopts Coal Work Integrated Control Technique

3 # coal seam in Xinjing Coal mine Yangquan Coal Industry is coal and gas outburst seam. Custom way we used to induce coal and gas outburst is vibration shot and mining shot. It is unsafe and reduced producing efficiency on working face seriously. The way of water injection with shallow boreholes in G - force reducing section on work face and gas drainage at G - force top point in wind lane throw gas hole could eliminate dangerous of coal and gas outburst on work face and improve production. It can eliminate danger coefficient of work face. Also it can improve production.
