中文摘要:
      矿井瓦斯是影响煤矿安全生产的主要灾害之一,研究其分布特征及控制因素是解决矿井瓦斯灾害问题的关键。本文测试了山西永聚煤矿的10号微风化煤的瓦斯含量、煤岩成分、埋深、煤孔隙特征和等温吸附参数。通过SPSS软件分析了煤层瓦斯含量与煤层组分、埋藏深度等进行了Person线性相关性分析,从而确定煤层瓦斯含量的主要控制因素和瓦斯分布规律。结果表明,10号微风化煤的孔隙主要为微孔和过渡孔,孔径介于10~800 nm,具有原生孔隙特征,表明其未收到风化作用的影响。其对瓦斯吸附具有随着压力增大而吸附量显著增加的特征,但压力大于6 MPa时,瓦斯的吸附不在随着压力增加。瓦斯含量与煤层的埋藏深度且具有良好的正相关线性关系,从而根据二者线性关系和煤层埋深,预测了瓦斯分布规律。
英文摘要:
      Coal mine gas is one of the main hazards of mining. In order to figure out the main geological factors of mine gas in Yongjǚ coal mine in Shanxi province, the contents of coal mine gas, compositions, absorption and buried depth of coal samples were tested. Then using the SPSS software for analysis of Person correlation between the coal gas content and their control factors, respectively. The results suggest that the pores of the light weathered No. 10 coal seams consist of micropores and transitional pores, mainly from 10 nm to 800 nm. Those pores are mainly primary pores implying that the coal textures were unchanged during the coal weather. The absorption volume increases by pressure. However, when the pressure beyond 6 MPa, the absorption of gas did not increase any more. The gas contents were not affected by the composition of coal, whereas, the gas contents have a good positive relationship with the depth of coal. Which allows to predict the distribution of coal gas.
