摘要
本文根据弹塑性力学和热力学理论,提出了煤层中原始瓦斯压力P与其埋深H之间的关系式,从理论上探讨了煤层中原始瓦斯压力的分布规律,并利用鱼田堡煤矿六号煤层的瓦斯压力统计结果对其进行了验证,结果表明,理论计算结果与统计分析结果是一致的。
On the basis of the elastic-plastic theory and the themodynamics theory, this paper has set up the theoretical equation between the gas pressure (P) and the depth (H) ,and has further probed into the distributive pattern of the primitive gas pressure in a coal seam. Then we have demonstrated the above theory by the in-situ statistic result of the primitive gas pressure in the 6th coal seam of the Yutianbao coal mine, the verified result has made clear that both the theoretical analysis and the in-situ gas pressure survey was very identical.
