【摘要】：根據(jù)趙固一礦地質(zhì)和水文地質(zhì)條件,分析了巷道掘進(jìn)和采煤過(guò)程中二1煤層底板L8灰?guī)r突水危險(xiǎn),提出采用超前注漿解決煤層底板突水。根據(jù)以往施工經(jīng)驗(yàn)總結(jié)了常用的井下煤層底板超前注漿防治水技術(shù),結(jié)合目前新技術(shù)的發(fā)展,研究了地面定向水平孔煤層底板超前注漿防治水技術(shù),并對(duì)兩種注漿防治水技術(shù)進(jìn)行了對(duì)比分析,闡述了其各自優(yōu)缺點(diǎn)及適用條件。結(jié)果表明,地面定向水平孔煤層底板超前注漿防治水技術(shù)適用于煤層底板防治水,并已經(jīng)取得了很好的效果。
[Abstract]:According to the geological and hydrogeological conditions of Zhaogu No. 1 Coal Mine, this paper analyzes the water inrush danger of L8 limestone in the floor of No. 2 coal seam during roadway excavation and coal mining, and puts forward the method of advanced grouting to solve the water inrush of coal seam floor. According to the previous construction experience, this paper summarizes the commonly used water prevention technology of underground coal seam floor, combining with the development of new technology at present, studies the water prevention technology of ground oriented horizontal hole coal seam floor. The advantages and disadvantages and applicable conditions of two grouting technologies for water prevention and control are compared and analyzed. The results show that the technology of water prevention and control by advanced grouting on the floor of horizontal hole coal seam is suitable for the prevention of water of coal seam floor, and it has achieved good results.
