综合物探技术在工作面防治水中的应用

The application of integrated geophysical exploration technique in the prevention and control of working face water

兴盛园煤矿地质及水文地质条件复杂,开采的1#、2#煤层为近距离煤层,带压程度较高,受周边小煤窑开采破坏严重。为超前探明1-101首采工作面地质构造及小窑破坏区范围,采用了矿井瞬变电磁法、探地雷达、音频电透视法等综合物探技术对1-101首采工作面进行地质探查,查明了工作面隐伏导水构造及小窑采空破坏区范围,为工作面的防治水工作提供了充足的地质依据。

Xingshengyuan coal mine complex geological and hydro -geological conditions of mining of 1 #,2 #coal seam of close distance coal seam,with pressure level is higher,the surrounding small mines mining damage.Is proven in advance 1 -101 initial mining damage zone of geological structure and small kiln of mine transient electromagnetic method,ground penetrating radar （GPR）is adopted,the integrated geophysical exploration technology such as audio frequency electric perspective of 1 -101 mining face in geological exploration,find out the working face of concealed guide structure and small kiln of goaf water damage zone,provides ample geological basis for the prevention and control of working face water.
