摘　　要：地质条件复杂的工作面由于勘探条件较差或者存在多种隐蔽致灾地质因素干扰,导致单一的物探手段难以准确辨识不良地质体,需要采用多种物探方法进行联合勘探,相互补充印证,以解决物探多解性问题。针对新义煤矿11080工作面揭露的大范围薄化带,采用地震槽波速度场、质量场、能量场以及无线电波透视法联合勘探,对不良地质体进行多维度、多方面的探查,开展多场耦合综合解译,圈出了工作面煤层薄化带和开采关注区。结果显示,多场联合勘探综合解译技术能够对复杂地质条件下极不稳定煤层进行有效探查,能够准确判断不良地质体的相关属性,为工作面安全高效生产提供依据,该方法能够在类似地质条件工作面推广。Due to poor exploration conditions or the presence of multiple hidden geological factors that can cause disasters in complex geological working faces,it is difficult to accurately identify unfavorable geological bodies using a single geophysical method.Therefore,it is necessary to use multiple geophysical methods for joint exploration to complement and confirm each other,and solve the problem of multiple interpretations in geophysical exploration.In response to the large-scale thinning zone exposed at the 11080 working face of Xinyi coal mine,a joint exploration of seismic trough wave velocity field,mass field,energy field,and radio wave penetration method was carried out to explore the unfavorable geological body in multiple dimensions and aspects.Multi-field coupling comprehensive interpretation was conducted to delineate the coal seam thinning zone and mining focus area at the working face.The results show that the comprehensive interpretation technology of multi-field joint exploration can effectively explore extremely unstable coal seams under complex geological conditions,accurately determine the relevant attributes of unfavorable geological bodies,and provide a basis for safe and efficient production in working faces.This method can be promoted in working faces with similar geological conditions.
