摘要
针对50901综放工作面回采时水害威胁类型,提出综合使用物探探测、疏排以及底板注浆改造等方式进行防治水。依据现场实际情况防治水技术方案进行设计,并进行工程应用。结果表明,50901综放工作面采用的综合防治水技术措施切实可靠,可确保采面回采安全。
In view of the type of water hazard threat during mining in 50901 fully mechanized top coal caving face,the comprehensive use of geophysical exploration,drainage and floor grouting transformation is proposed to prevent water.The technical scheme for water prevention and control shall be designed according to the actual situation on site and applied in the project.The results show that the comprehensive water control measures adopted in 50901 fully mechanized top coal caving face are practical and reliable,which can ensure the safety of mining face.
