| 摘 要： | 煤层瓦斯压力是评价煤层突出危险性与决定煤层瓦斯含量的一个重要指标,与瓦斯突出关系紧密.为了掌握煤层瓦斯压力分布规律及普遍适用的预测方法,本文通过分析煤层瓦斯压力分布规律及其影响因素,提出了煤层瓦斯压力计算的理论公式及采用安全线预测煤层瓦斯压力的新方法.通过对比分析表明,采用安全线图解法预测煤层瓦斯压力,能较准确反映实测结果,在现场实践运用中合理、可靠,能够为矿井深部瓦斯治理提供安全可靠的依据,保证矿井安全生产.

| Abstract: | Gas pressure is an important index for evaluating outburst risk and for determining gas content in coal seam.So it is closely related with coal and gas outburst.For mastering the distribution rule and the commonly used forecasting method of gas pressure in coal seam,we proposed a theoretical formulas for computing gas pressure and a new method for forecasting gas pressure using safety line method.The results show that the safety line method could exactly reflect fact by comparative analysis on a lot of proj... |
