中文摘要：

为了确定煤层区域预测瓦斯含量指标临界值,采用高压吸附煤样密封罐原煤煤样瓦斯吸附—解吸平衡实验法,测试分析了瓦斯压力和含量变化规律,研究了瓦斯压力指标临界值对应的瓦斯含量.同时,现场试验考察了瓦斯含量与突出危险的关联性,确定了无明显突出预兆的瓦斯含量.结合防突规定,优选了适用的区域预测瓦斯含量指标临界值,探索了综合实验、现场考察和防突规定确定区域预测瓦斯含量指标临界值的新途径.

英文摘要：

To determine the critical value of predicted regional gas content,gas pressure and gas content of original moisture coal samples were studied by original coal samples gas balance method in a sealed coal sample tank ,the experimentation is conducted to examine the changes of gas pressure and content, the gas content corresponding to critical value of gas pressure was also studied, it the same time,the experiment is performed to examine the relation between gas content and gas outburst danger. Gas content without obvious outburst indication was determined, too. Combining with outburst prevention and control regulations, reasonable critical value of regional predicted gas contents were chosen ,the new paths of determining critical value of regional predicted gas content mere also explored com- bining comprehensive experiment, the field study, outburst prevention and control regulations.
