屯兰煤矿为煤与瓦斯突出矿井,2号和8号煤层地质结构复杂,瓦斯含量高,煤层瓦斯压力大,为了高效抽采煤层瓦斯,消除突出危险性,进行区域预抽,屯兰煤矿引入VLD-1000定向钻机,在不断的应用过程中针对屯兰煤矿的实际情况,总结经验进行应用创新,在2号和8号煤层成功应用VLD-1000定向钻机进行一钻多孔施工,多次突破800 m的钻孔深度记录,并且提高了抽采效果,缩短了抽采时间,保证了矿井抽、采、掘平衡。
Tunlan coal mine is a coal and gas outburst mine. The coal seam No. 2 and No. 8 have complex geological structure, high gas content and large gas pressure. In order to efficiently extract coal seam gas and eliminate prominent danger, pre-pumping in the area, Tunlan Coal Mine Introduced the VLD-1000 directional drilling rig, in the continuous application process for the actual situation in Tunlan Coal Mine, summarize the experience of application innovation in the No. 2 and No. 8 coal seam successfully applied VLD-1000 directional drilling machine for drilling a multi-hole construction, many breakthroughs 800 m drilling depth record, and improve the pumping effect, shorten the extraction time, to ensure mine pumping, mining, digging balance.
