褶皱中和面对煤层的控制性研究

Controlling effect of the fold neutral plane on coal bed

利用纵弯褶皱变形中中和面上下岩层的不同应力与应变特点,分析了处于褶皱中和面上下各煤层在背斜与向斜部位煤层厚度、煤层构造、煤体结构及煤层瓦斯的赋存规律与差异性,揭示了这些现象产生的原因。该研究对于开展煤层厚度、煤层构造及煤与瓦斯突出的预测研究提供了理论依据。

By means of stress- strain feature of upper and lower strata of fold neutral plane in the course of longitudinal fold formarion, the differences between the upper coal bed and lower coal bed of fold neutral plane are analyzed from the coal thickness, coal structure, coal body structure, combed gas occurrence and diversifies etc., revealing the cause of these appearances. The investigation provides theory basis for forecasting coal thickness, coal bed structure, and coal and gas outburst in fold area.
