【摘要】：為了研究西部礦區(qū)淺埋煤層開采造成的地裂縫災(zāi)害,以神東礦區(qū)為研究基地,對大柳塔礦22201,52304工作面開采的地裂縫進行了持續(xù)動態(tài)監(jiān)測,研究了采動地裂縫的動態(tài)發(fā)育規(guī)律,建立了采動地裂縫發(fā)育深度和寬度、落差之間的定量函數(shù)關(guān)系模型,在此基礎(chǔ)上,提出了采動過程中的臨時性地裂縫治理標準和依據(jù)。研究表明:隨著工作面的推進,采動過程中的臨時性裂縫呈現(xiàn)"增大-減小-閉合"的動態(tài)規(guī)律;地裂縫發(fā)育深度與寬度之間存在線性增大的正比例關(guān)系,深度與落差之間存在對數(shù)關(guān)系;為保證安全生產(chǎn),當"由上到下"擴展的地裂縫與"自下而上"發(fā)育的導(dǎo)水裂隙帶貫通時,臨時性裂縫需要治理,治理標準為導(dǎo)水裂隙帶高度與地裂縫深度之和大于煤層埋深,治理依據(jù)為裂縫最大安全寬度或最大安全落差。
[Abstract]:In order to study the ground fissure disaster caused by the shallow coal seam mining in the west mining area, taking Shendong mining area as the research base, the continuous dynamic monitoring of the ground fissure in the mining face of Daliuta Coal Mine (22201) 52304 is carried out, and the dynamic development law of the mining ground crack is studied. A quantitative functional model of the depth, width and drop of fractures in mining ground is established, and on the basis of this model, the standard and basis for the treatment of temporary ground fractures in the process of mining are put forward. The results show that: with the advance of the working face, the temporary cracks in the mining process show the dynamic law of "enlarging, decreasing and closing", and there is a positive proportion between the depth and width of the ground fractures. There is a logarithmic relationship between depth and drop, and in order to ensure safe production, temporary cracks need to be treated when the "top-down" extended ground fractures are connected with the "bottom-up" water-conducting fissure zone. The treatment standard is that the sum of the height of the water-conducting fissure zone and the depth of the ground fissure is greater than the buried depth of the coal seam, and the treatment is based on the maximum safe width of the fracture or the maximum safety drop.
