【摘要】：從金竹山礦區(qū)地質(zhì)構(gòu)造特征出發(fā),對(duì)其斷裂和褶皺構(gòu)造特征進(jìn)行研究,發(fā)現(xiàn)礦區(qū)構(gòu)造較為復(fù)雜,礦區(qū)范圍內(nèi)次一級(jí)褶曲較少,主要分布于西北翼,斷層較發(fā)育,主要發(fā)育于井田邊界及兩翼淺部,以逆斷層為主,正斷層次之。通過分析礦區(qū)內(nèi)各構(gòu)造的活動(dòng)強(qiáng)度,建立構(gòu)造運(yùn)動(dòng)生熱的數(shù)學(xué)模型對(duì)斷裂摩擦熱能釋放量進(jìn)行模擬,通過估算對(duì)比金竹山礦區(qū)西北翼和東南翼煤層斷面活動(dòng)的生熱量,發(fā)現(xiàn)西北翼煤層斷層面總生熱量較高,東南翼僅八十亭斷層規(guī)模較大,為5.04×1011J,而且東南翼逆斷層多與附近的正斷層溝通,造成應(yīng)力釋放,使得早期生成的瓦斯得到有效的逸散,整個(gè)東南翼斷層附近的煤與瓦斯突出的為危險(xiǎn)級(jí)別要小于西北翼。
[Abstract]:Based on the geological structure characteristics of Jinzhushan mining area, it is found that the fault and fold structure are more complicated, the secondary fold is less in the mining area, mainly distributed in the northwest wing, and the faults are relatively developed. It is mainly developed in the boundary of the mine field and the shallow part of the two wings, mainly with the reverse fault, followed by the normal fault. Based on the analysis of the active strength of the structures in the mining area, a mathematical model of tectonic heat generation is established to simulate the thermal energy release from the fracture friction. The heat generation and heat generation of the coal seam cross section in the northwest wing and southeast wing of Jinzhushan mining area are estimated and compared. It is found that the total heat generation in the fault plane of the northwest wing coal seam is relatively high, and the scale of the fault in the southeastern wing is only larger, which is 5.04 脳 1011J, and the thrusting fault of the southeast wing communicates with the nearby normal fault, which results in the stress release and the effective emission of the gas generated in the early stage. The danger level of coal and gas outburst near the fault in the southeast wing is smaller than that in the northwest wing.
