摘要:
用地质的观点研究煤层瓦斯赋存已获得实践检验，瓦斯赋存与地质因素密切相关。通过井下实测煤层原始瓦斯含量，选择各项煤层参数均达到要求的瓦斯含量数据，绘制瓦斯含量等值线，分析了两条断层之间煤层的瓦斯含量分布规律。绘制研究区域特定位置的煤厚、瓦斯含量剖面图，定性、定量地分析了断层对煤层产状、煤厚等煤层赋存条件的影响及其对瓦斯赋存规律的控制作用。结果表明，研究区域内的煤层及瓦斯分布受断层影响较大：沿煤层走向，煤厚呈现出“高-低-高-低”的变化，卸压带和应力集中带交互出现，瓦斯含量呈现“低-高-低-高-低”的分布规律
Abstract:
The study on coal seam gas occurrence with the geological view has got practice test, and gas occurrence is closely related to geological factors. Through testing the original gas content in coal seam by underground on-site measurement, the gas content data of coal samples that all the coal seam parameters could meet the requirements were selected to draw the contours of gas content. The distribution laws of gas content in coal seam between two faults were analyzed. The cross-sectional views of coal seam thickness and gas content in particular location of study area were drawn, and the impact of the fault on the coal seam occurrence conditions, such as coal seam attitude and coal seam thickness, and its control action on gas occurrence law were analyzed qualitatively and quantitatively. The results showed that coal seam and gas distribution in the study area were greatly influenced by faults. Along the coal seam trend, the coal seam thickness showed a "high-low-high-low" variation law, the pressure relief zone and stress concentration zone occurred alternately. The gas content presented a "low-high-low-high-low" distribution law, and along the coal seam tendency, the gas content showed decreasing trend as the depth increased, and the area of less than 8m3/t was reducing.
