摘要
针对余吾煤矿长钻孔施工过程中出现的成孔率低和卡钻问题,根据实际情况对钻孔的布置进行了优化,并对钻孔的轨迹进行了设计。在布置钻孔时,采用了纵向和横向2种方式,而钻孔的轨迹采用三段施工。希望所述内容可以为日后千米钻孔的施工提供一定的指导。
Aiming at the problems of low hole forming rate and sticking in the construction of long boreholes in Yuwu Coal Mine,the layout of boreholes was optimized according to the actual situation,and the trajectory of boreholes was designed.In the layout of drilling holes,two methods of longitudinal and transverse were adopted,and the trajectory of drilling holes adopted three-stage construction.It is hoped that the above contents can provide some guidance for the construction of kilometer drilling in the future.
