摘要
在长钻孔实际施工过程中,利用定向钻进技术和自己研制的配套器件,结合力学理论,保证钻孔的实际运行轨迹在设计允许偏差内,以确保钻孔的终孔点在设计的范围内,达到安全有效的抽采工作面瓦斯的目的,防止钻孔误透巷道及采空区,造成事故及形成安全隐患。
Orientation technology and the developed direction regulator were used combining with mechanics theory to keep bore holes within designed windage and the ends of bore holes within designed bound, to get better effectiveness of methane extraction, to prevent bore holes from going through tunnel and gob area, and to prevent disaster from happening or form becoming hidden problems of safety in drilling operation.
