河南某煤矿地质特征及三维地震勘探应用

Geological features of a coal mine in Henan and application of 3D seismic exploration

河南某煤矿可采煤层包括二2煤层和三2煤层,本文详细分析了二2煤层和三2煤层的地层特征和煤层特征,认为二2煤层为全区大部可采,三2煤层为局部开采。采用波形振幅和钻孔揭露相结合的方法,预测二2煤层一般厚度大于2 m,煤层较稳定,利于开采,而三2煤层厚度小于1 m,不具备开采价值。

The minable coal seams of a coal mine in Henan province includeⅡ2 coalbed andⅢ2 coalbed.This paper analyzed the stratum features and coal seam features ofⅡ2 coalbed andⅢ2 coalbed in detail.It was considered that the majority ofⅡ2 coalbed was mineable in the whole area,andⅢ2 coalbed was partially mined.It was predicted that the thickness ofⅡ2 coalbed is more than 2 m and the coal seam is more stable,which is favorable for mining.However,the thickness ofⅢ2 coalbed is less than 1 m,so it has no mining value.
