【摘要】：本文針對(duì)神南礦區(qū)做研究,通過查閱大量的資料以及統(tǒng)計(jì)等,運(yùn)用水文地質(zhì)學(xué)、構(gòu)造地質(zhì)學(xué)等相關(guān)學(xué)科,結(jié)合研究區(qū)內(nèi)的鉆孔資料以及勘探報(bào)告等各種資料,對(duì)神南礦區(qū)煤層開采對(duì)地下水的影響做了深入研究,并且提出了相關(guān)的防治措施。研究區(qū)內(nèi)構(gòu)造相對(duì)簡(jiǎn)單,總體為單斜構(gòu)造。神南礦區(qū)目前主要開采的煤層包括1-2煤、2-2煤、3-1煤、4-2煤和5-2煤,通過各個(gè)主采煤層的賦存特征和研究區(qū)內(nèi)地層特征,分析出主采煤層其頂?shù)装鍘r性特征;通過研究區(qū)內(nèi)水文地質(zhì)特征條件,分析出研究區(qū)主要含水層和隔水層性質(zhì);綜合上述兩個(gè)特征條件,總結(jié)出研究區(qū)內(nèi)主要可采煤層與主要含水層之間的聯(lián)系。本文主要是通過公式法對(duì)研究區(qū)各個(gè)主采煤層的冒落帶和導(dǎo)水裂隙帶進(jìn)行計(jì)算,通過“兩帶”高度與主采煤層與主要含水層之間的距離作比較,得出煤層開采主要影響的含水層;再根據(jù)研究區(qū)內(nèi)主采煤層抽水試驗(yàn)數(shù)據(jù),對(duì)其影響半徑進(jìn)行計(jì)算,得出主采煤層影響的半徑范圍,并且對(duì)煤層開采過程提出一定性的建議和評(píng)價(jià)。
[Abstract]:In this paper, a lot of data and statistics are consulted, and some related subjects, such as hydrogeology, tectonic geology, and so on, are used to study Shennan mining area, and all kinds of data such as borehole data and exploration report are combined in the study area. In this paper, the influence of coal seam mining on groundwater in Shennan mining area is deeply studied, and relevant prevention measures are put forward. The structure in the study area is relatively simple, and the whole structure is monoclinic. At present, the coal seams mainly mined in Shennan mining area include 1-2 coal seam 2-2 coal seam 3-1 coal seam 4-2 coal and 5-2 coal seam. Through the occurrence characteristics of each main coal seam and the stratigraphic characteristics of the study area, the characteristics of roof and floor slate rock of main mining coal seam are analyzed. Based on the hydrogeological characteristics in the study area, the properties of the main aquifer and aquifer in the study area are analyzed, and the relationship between the main minable coal seam and the main aquifer in the study area is summarized by synthesizing the above two characteristic conditions. In this paper, the caving zone and the water-conducting fissure zone of each main coal seam in the study area are calculated by formula method, and the distance between the "two zones" and the main coal seam and the main aquifer is compared by means of the height of the "two zones". According to the experimental data of pumping water from the main coal seam in the study area, the influence radius of the main coal seam is calculated, and the radius range of the influence of the main coal seam is obtained. And put forward some suggestions and evaluation to coal seam mining process.
