摘要
为了提高煤矿企业在瓦斯抽采的效果和降低抽采成本,解决长距离抽采孔、注浆孔和穿层孔等各种瓦斯抽放孔,研制出了6000ZYWLDF分体式定向全液压钻机。通过井下工业性试验情况,总结了该钻机在粉砂岩以及破碎煤层中钻孔施工情况,施工结果证明6000ZYWLDF分体式定向全液压钻机比同类型的钻机在成孔率和钻孔深度方面有着明显的优势。
In order to improve the coal mine enterprises in the gas drainage effect and reduce the extraction cost, solve the long-distance drainage hole, grouting hole and wear layer hole and other gas drainage hole, developed 6000 ZYWLDF split directional hydraulic drilling rig. Through underground industrial test,summarizes the rig in siltstone and broken coal seam drilling construction, the construction results prove that 6000 ZYWLDF split directional hydraulic drill rig in the same type than the hole forming rate and drilling depth has obvious advantages.
