【摘要】：為解決含水層下煤層開采所導(dǎo)致的潰水災(zāi)害問題,提出了基于固體充填采煤的保水開采方法,闡述了該方法的基本原理,分析了固體充填開采覆巖導(dǎo)水裂隙演化特征,并基于固體充填開采導(dǎo)水裂隙帶高度預(yù)計(jì)公式,結(jié)合《建筑物、水體、鐵路及主要井巷煤柱留設(shè)與壓煤開采規(guī)程》,建立了含水層下固體充填開采臨界充實(shí)率計(jì)算模型,分區(qū)設(shè)計(jì)了受含水層影響煤層的充實(shí)率,進(jìn)而對(duì)煤層進(jìn)行了充填工作面設(shè)計(jì)布置。五溝煤礦CT101充填工作面應(yīng)用結(jié)果表明:實(shí)測充采質(zhì)量比平均值為1.32,大于理論設(shè)計(jì)值1.28,充填效果較好,且導(dǎo)水裂隙帶高度僅為10.0 m左右,該方法有效地降低了覆巖導(dǎo)水裂隙帶高度,可實(shí)現(xiàn)含水層下保水開采的目標(biāo)。
[Abstract]:In order to solve the problem of water collapse caused by coal seam mining under aquifer, a water retaining mining method based on solid filling coal mining is put forward, the basic principle of this method is expounded, and the evolution characteristics of water conductivity fractures of overburden rock in solid filling mining are analyzed. Based on the prediction formula of the height of water-conducting fissure zone in solid filling mining, combined with the rules of Coal Pillar retention and Coal Mining in buildings, Water bodies, Railways and main roadways, a calculation model for critical enrichment rate of solid filling mining under aquifer is established. The filling ratio of coal bed affected by aquifer is designed and the design arrangement of filling face is carried out. The application results of CT101 filling face in Wugou Coal Mine show that the average value of the measured filling quality ratio is 1.32, which is larger than the theoretical design value of 1.28, and the filling effect is better, and the height of the water-conducting fissure zone is only about 10.0 m. This method can effectively reduce the height of the overburden water conductivity fracture zone and realize the goal of water conservation mining under the aquifer.
