【摘要】 为防止煤矿在回采过程中发生水害事故,常釆用物理探测方法对前方未开采区域进行地质预报,其中瞬变电磁法(以下简称TEM)已成为煤矿采区水文物理探测的一种主要手段。基于TEM井下全空间的探测理论对黑龙江省某煤矿井下工作区进行探测,数据采集、检验、处理后形成视电阻率截面图,依据视电阻率截面图对探测区的富水性进行分析。探测结果显示:探测区的富水性很强,富水异常区靠近采空区和断层。此方法为井下回采工作面提供有效的地质信息和技术指导,以防止水害事故的发生。更多还原

【Abstract】 In order to prevent the coal mine water disasters accidents occurred in the process of mining,often adopt physical detection methods for the front not mining area geological forecast. The transient electromagnetic method(TEM) has become a major coal mining area hydrology physical detection method,based on the theory of TEM detection of underground space in a certain coal mine of Heilongjiang province workspace. After data collection,inspection,processing formation apparent resistivity section map. On the basis of apparent resistivity section diagram to analyze and detect rich water-based. Detection results show that detect area water is very strong,rich water anomaly area near the mined-out area and fault. This method for underground working face effective geological information and technical guidance,to prevent water damage accidents.更多还原
