摘要
随着煤炭资源开采,采煤深度也在不断增加,灰岩水害对煤矿安全的威胁也越加严重。以淮南潘二煤矿西四采区为研究对象,为保障A组煤的正常开采,对煤层底板采用多分支水平井注浆技术进行超前治理,文章以D5孔组为例,针对治理区域地质概况研究分析工程的技术难点,并提出应对措施。
With the exploitation of coal resources,the depth of coal mining is also increasing,and the threat of limestone water damage to coal mine safety is becoming more and more serious.Taking the coal mining area of Paner Xisi in Huainan as the research object,in order to ensure the normal mining of Group A coal,multi-branch horizontal well grouting technology is adopted to advance control of coal seam floor.Taking the D5 hole group as an example,this paper analyzes the technical difficulties of the research project for the geological situation of the governance region,and puts forward the corresponding measures.
