摘要
通过对现场大量煤样测试结果的分析研究 ,认为采用指标气体法早期预报煤炭自然发火是可行的 ,实际应用效果也很理想 ,但同时也指出不同矿井所选用的指标气体不同 ,甚至同一煤层不同采区所选用的指标气体也不尽相同 。
Based on the analytical research on the test results from large amount of coal samples, the article thinks that it is feasible to make early forecast of spontaneous coal combustion by taking advantage of indicator gas and ideal results have been obtained therefrom. However, the article points out that different indicator gases should be selected in different mines and even in different mining sections in the same coal seam, attention should be given to a careful selection of different indicator gases. The crux is to carry out on-the-spot sampling and testing.
