摘要
晋能控股煤业集团岳城煤矿引进了ZDY12000LD定向钻机,解决了15号煤因煤层赋存薄、夹矸多、局部区域煤体酥碎等因素影响,预抽钻孔塌孔、压钻、见矸等问题,成孔率及抽放量都有显著提升,为后期采掘区域的安全生产创造了条件。
ZDY12000LD directional drilling rig was introduced into Yuecheng Coal Mine of Jinneng Holding Coal Group,which solved the problems of pre-pumping borehole collapse,pressing drilling and seeing gangue in the No.15 due to the influence of thin coal seam,many gangue entrapment and crisp coal in local area,the hole formation rate and drainage volume were significantly increased,which created conditions for the safe production of mining area in the later stage.
