地球物理勘探在基建矿井的应用分析
|
摘要
山西晋煤集团临汾晋牛煤矿投资有限责任公司(以下简称晋牛煤矿)位于河东煤田东北部。区内基岩局部出露,黄土主要覆盖在梁坡上,地形地貌复杂,切割强烈,沟谷纵横,多呈"V"字形,相对高差280m。浅层出露岩性种类较多,且相间带状分布,主要岩性为砂质粘土、粘土砂砾石层及松散洪积物等。区内中北部多有黄土覆盖,大多3~10m,其间赋存多层厚度不等的钙质结核,成孔困难,激发条件差。晋牛煤矿共施工地球物理勘探面积6.02km2,解释断层8条,陷落柱2个,采空区11个,取得了丰富的地质成果。
Located in the northeast Hedong coalfield,Linfen Jinniu Coal Mine Investment Co.,Ltd.,Shanxi Jincheng Coal Industry Group(abbreviation:Jinniu Colliery)is largely bedrock outcropped and of rare occurrences loess covered.Loess covering the main beam slope,complex topography,cutting strong,gully aspect,mostly"V"shaped,its relative height difference is 280 m.More types of shallow strata outcropped lithology,and alternate with zonal distribution,the main lithology is sandy clay,clay and gravel layer and loose diluvium,etc..Loess covering mostly area in north-central,mostly 3~10m,multi-layer of thickness calcareous concretion exists,pore forming is difficult,shot condition is poor.6.02km2 of geophysical exploration has been carried out in Jinniu Colliery,8faults 2subsided columns and 11mined-out areas,which obtained abundant geological results.
