摘要
为了探明正帮煤矿11104工作面不良地质体构造和煤的赋存情况,利用测井仪对该工作面40个钻孔进行孔中物探。结果表明,11104工作面煤的视电阻率处于中低值,低于铝土矿,高于砂岩和泥岩,而煤的自然伽马处于最低值;利用自然伽马数据构建地质构造正演模型,获得的不良地质体构造与实际冲刷带地质赋存吻合度较高;利用煤岩精细化解释获得的综合测井柱状图与地质构造正演模型模拟的煤层赋存情况基本一致,说明正演模型不仅对冲刷带响应准确,而且对煤的发育规律也具有实际应用价值。利用综合物探方法构建的正演模型为今后类似地质条件的探测提供了借鉴参考。
In order to find out the occurrence of unfavorable geological body structure and coal in No.11104 Face of Zhengbang Coal Mine,40 boreholes in the working face were geophysically explored by logging instrument.The results showed that the apparent resistivity of coal in No.11104 Face was in the middle and low value,lower than that of bauxite,higher than that of sandstone and mudstone,while the natural gamma of coal was at the lowest value.Using natural gamma data to construct a geological structure forward model,the obtained unfavorable geological body structure was in good agreement with the actual geological occurrence of the erosion zone.The comprehensive logging histogram obtained by the fine interpretation of coal and rock was basically consistent with the coal seam occurrence simulated by the geological structure forward model,indicating that the forward model not only responded accurately to the erosion zone,but also had practical application value for the development law of coal.The forward model constructed by the comprehensive geophysical exploration method provided a reference for the detection of similar geological conditions in the future.
