古汉山矿15081面水害治理关键技术

Key Techniques of 15081 Working Face Water Damage Control in Guhan Mountain Mine

为解决古汉山矿15081工作面水害及确保工作面高效安全生产,采用地面精准定向钻孔技术与地面注浆技术对二1煤层底板L8灰岩实施加固。针对精准定向钻孔技术、地面注浆的注浆设备、注浆工艺流程、注浆量计算方法及注浆结束标准及封孔进行分析与研究,分析与阐述了古汉山矿15081工作面注浆量影响因素及解决方案。

In order to solve water damge and ensure the efficient and safe production for the 15081 working face of Guhan mountain mine,it is proposed to using the ground accurately directional drilling grouting technology to reinforce 2nd coal seam L8 floor limestone.Accurately directional drilling technology,grouting equipment,calculation method of grounting amount and grouting end standard and sealing are analyzed and studyed for the project,at the same time,the influencing factors and solutions of the grouting amount of 15081 working face in Guhan mountain mine are analyzed and explained.
