针对大雁二矿的锚网—锚杆—锚索联合支护技术降低掘进速度的问题,通过现场分析和试验,决定拆除原锚索施工设备,改用煤电钻和SDB手动打压泵。现场应用证明,煤电钻体积小、重量轻,便于工人操作,大大提高了工效。 Aiming at the problem of reducing the heading speed by the combined support technology of anchor net, anchor rod and anchor cable in Dayan No.2 Mine, through the on-site analysis and test, it is decided to dismantle the original anchor cable construction equipment and switch to coal electric drill and SDB manual pressure pump. Field application shows that coal drill small size, light weight, easy for workers to operate, greatly improving the work efficiency.
