针对目前煤矿井下使用的钻机中心普遍偏低,均是单层钻孔,无法实现分层钻孔,不能满足软煤层、透气性差、瓦斯含量高等特殊地质条件下抽放瓦斯的工艺要求,设计了一种深孔钻车在能够满足大断面高层钻瓦斯孔的需求,满足不同高度、不同角度的施工要求,更适应多打孔、深打孔、密集抽放瓦斯孔的工艺要求。
In view of the low center of drilling rig currently used in coal mines, it is a single-layer drilling, can not be achieved by stratified drilling, can not meet the technical requirements of drainage gas under special geological conditions of soft coal seam, poor gas permeability, high gas content, designed A deep hole drilling rig is capable of meeting the requirements of high-level drilling gas holes in large sections and meeting the requirements of construction at different heights and angles, and more adapts to the technical requirements of multi-drilling, deep drilling and intensive drainage of gas holes.
