摘要
为了解决晋煤胡底矿瓦斯含量大、采掘困难的问题,通过试验施工L型井,来实现地面抽放瓦斯的目的。提出了用MWD无线随钻仪器,通过多次绕障技术来避开井下漏水部位。实践表明:利用先进的无线定向技术,能够解决井下的复杂问题,从而达到钻井目的。该方法的运用,确保了L型井的顺利完工,为矿井瓦斯的顺利抽放赢得了时间。
To solve the problems of large gas concentration and driving difficulty in Hudi Coal Mine of Jincheng Anthracite Mining Group, through the experiment of construct L-type mine shaft, the gas was drained to ground. It was proposed to avoid the mine shaft water leakage spot by using wireless along with drills the instrument with MWD. The practice application indicated that ,by using the advanced direction- al technology, complex problems of the mine shaft can be solved, and can achieve the goal of constructing mine shaft. This utilization of method has guaranteed the smooth eonstruetion of L-type mine shaft,and has won the time for the successful drainage of gas.
