摘要
并行网络直流电法因可在工作面任意布设电极,可快速实现三维电阻率探测,地震反射共偏移法原理为反射波勘探原理,采用多次覆盖观测系统开展井下数据采集;为了探查华北某煤矿西六采区陷落柱发育特征及其赋水性,确保回风上山掘进安全,基于这两种物探方法在皮带巷和轨道巷布设了两条测线,经过井下数据采集、室内资料处理与分析,得到了电阻率反演剖面和地震反射剖面,结合地质资料,对陷落柱的电性特征及结构进行研究。结果表明:陷落柱岩层连续性差,岩体较破碎;陷落柱底界发育深度超过底板60 m;陷落柱探查范围内及周围赋水性较弱。
The advantage of three-dimensional parallel electric surveying is that the electrode could be laid arbitrarily and data acquisition is fast. The principle of seismic reflection total deviation detection technology is reflection wave exploration,and the method of data collection underground is multiple coverage. In order to explore the developing stratum and the water content of the collapse column in North China,and to ensure the safety of the return air and uphill,Two survey lines based on parallel electric surveying and reflection total deviation detection technology are laid out. By data acquisition and processing analysis,resistivity profile and reflection seismic profile was obtained. Combined with geological data,electrical character and structure of collapse column was studied. The result shows that:( 1) the continuity of strata in the collapse column is bad,and rocks is crushing;( 2) the bottom boundary of the collapse column exceeds 60 m;( 3) the water content of the collapse column is weak.
