摘要
近几年来,随着我国国民经济的快速发展,对煤炭的需求也在不断增长,提高岩巷的掘进效率成了重中之重。为了解决目前巷道掘进过程存在的问题,研发一种能适应岩巷掘进工作面锚杆支护的煤矿用液压锚杆钻车,解决井下生产中遇到顶板岩层较硬时工作面施工锚杆锚索钻孔效率低、进度慢,影响掘进效率的被动局面。
In recent years,with the rapid development of national economy,the demand for coal is constantly increasing,and improving the digging efficiency of rock lanes has become a top priority.In order to solve the problems in the current roadway excavation process,a kind of coal mine hydraulic anchor rod drill that can adapt to rock roadway excavation working face anchor bolt support was developed to solve the problem of low efficiency and slow progress in drilling bolt andt when the roof rock formation is hard in underground production.
