唐家河煤矿水动力对瓦斯赋存的控制机理研究

Research on Control Mechanism of Hydrodynamic Force on Gas Occurrence in Tangjiahe Coal Mine

在瓦斯基础参数和地质资料综合分析的基础上,系统地研究了唐家河井田水动力条件对瓦斯生成、运移和后期保存的控制机理。结果表明:水动力活动影响着热成因生气阶段的古地温条件和煤体中瓦斯的吸附-解吸程度及其储层压力,进而影响着煤变质程度和瓦斯富集区。

Based on the comprehensive analysis of gas parameters and geological data, the control mechanism of hydrodynamic conditions on gas generation, migration and preservation were studied systematically in Tangjiahe mining field.The results show that hydrodynamic activities controlled paleogeothermal conditions in thermogenic gas generating period, storing pressure and the degree of gas adsorption and desorption in coal, which affected coalification degree and gas enrichment area.
