【摘要】 吴堡矿区赋存着丰富的煤炭资源,但开采技术条件较复杂,其中水文地质条件复杂是影响煤炭开采的主要不利开采技术条件。本文依据横沟井田勘探资料,较全面地分析了井田水文地质条件,并着重评价了井田矿井充水因素。认为黄河水对横沟井田煤炭开采无影响;奥灰承压水对山西组煤层开采在正常地段不会造成危害,对太原组煤层开采有很大的威胁。并提出太原组煤层能否开采利用,还需进一步作详细地质勘查研究工作。更多还原

【Abstract】 The Wubu coal fields are abundant in coal resources.Mining conditions in the fields are complicated,in which complex conditions of geohydrology is the major factor that impact coal mining in this coal fields.According to exploration information of the Henggou coal mine, this paper has made all-around analysis of the geohydrological conditions in the coal fields,assessed the water filling factors in coal mines and reached the following conciderations: water from the Yellow River is no impacts to coal mining in the Henggou coal mines;the Aohui confined water may not cause damages to mining the coal beds of the Shanxi Formation in normal sections,but would be a source of danger to coal mining in the Taiyuan Formation.It is required to do further detail geological exploration for making sure the possibility of coal mining in the Taiyuan Formation.更多还原
