我国煤矿地质、水文地质条件总体上十分复杂,据统计,在大中型煤矿中有500多个工作面受水害威胁,所以水文地质类型划分对煤田开采工作能否顺利进行非常重要.以往对该矿井地质勘查工作有地质填图,工程测量,钻探工程和测井四个方面的资料.现对干井田的地质情况重新整理分析：井田位于晋城国家规划矿区高平西区,为黄土丘陵区,第四系黄土、红色亚粘土大面积覆盖,地表有零星基岩出露.主要含煤地层石炭系上统太原组及二叠系下统山西组,留存厚度16.70-124.59m,共含煤1-10层,含煤厚度1.90-16.51m,含煤系数为9.77%,9#、15#为井田内稳定可采煤层,3#煤层虽稳定可采,但井田内大部已剥蚀.15#煤层分叉后的15-1#煤层虽可采但面积很小.通过地质勘查分析,对该矿区水文地质类型划分为松散岩类含水岩组,碎屑岩类含水岩组,碎屑岩夹碳酸盐岩类含水岩组,碳酸盐岩类含水岩组,中、上石炭统泥岩、铝质泥岩隔水岩组,碎屑岩类层间隔水岩组六个组,并确定了井田的水文地质情况.最后,给出矿井防止水害的各方面建议.

Answer 1

Our coal mine geology and hydrogeology conditions in general is very complex, according to statistics, in the medium and large coal mining in more than 500 by flood threat, so hydrogeology types of coal extraction into work will go smoothly is very important. The mine geology exploration of previous work has geological mapping, engineering survey, drilling engineering and logging four aspects of the material. Now the geological condition of dry compartmentalized rearrange the analysis: review made by the state planning mining area is located in no.1 gaoping west area, for loess hilly-gully loess, red and fourth is large, the surface covered clay sporadic bedrock the exposed. Main coal-bearing strata in the carboniferous taiyuan formation and ec Permian series of shanxi formation, under 124.59 16.70 - retained thickness of coal altogether m, 1-10 layers, including coal thickness 16.51 m, including - 1.90 9.77% coal coefficient for nine #, 15 # for field recognize base-level cycle within 3 # stable, although stability recoverable coal, but most have erosion within compartmentalized. 15 # 15 - after the forking seam 1 # coal seam is recoverable but the area is very small. Through analysis of the geological exploration, mining hydrogeology types are classified as loose aquifer rocks of clastic rock formations, such water rock formations, clastic rock contains carbonate rock class water rock formations, carbonate rock group, of water in the upper carboniferous mudstones, aluminum mudstone water-barrier rock formations, clastic rock group of layer of water between six, and confirmed the hydrogeological situation compartmentalized. Finally, we give mine prevent all aspects of water disasters suggestion.
