鸟山矿井区域防突设计

Niaoshan mine regional outburst prevention design

为防治矿井的煤与瓦斯突出,设计采用开采保护层和预抽煤层瓦斯等两项区域防突措施进行矿井区域防突设计,其中开采保护层防突措施中明确了保护煤层和被保护煤层,并确定保护范围;预抽煤层瓦斯防突措施中采用井下穿层钻孔预抽方法预抽瓦斯。以上两项区域防突措施在鸟山矿井井下开采得到应用,取得了较好的防突效果。

For the prevention and control of coal and gas outburst in mines, the design adopts the mining protective layer and the pre-pumping coal gas and other two regional outburst prevention measures, used mining the protective layer to prevent outburst, and determine the protected coal seam and the scope of protection seam, using the through beds hole for pre-pumping gas. The above two has been applied regional outburst prevention measures in niaoshan mine, and achieved good effect of preventing outburst.
