抚顺老虎台矿是一个自然发火非常严重的矿井,一般发火期为1～3个月,最短只有14天。几十年来我们用河砂、黄泥充填来控制和消灭矿井火灾,起到了很大的作用。在早期预防方面,我们应用采集煤在不同发火阶段的气样,用2307气相色谱仪分析,进行预测预报,也取得了明显的效果。但是预测预报的准确性主要是采气部位是否达到发火部位,多年来的实践证明,距离发火部位越
Fushun Tiger Taiwan mine is a natural fire very serious mine, the general period of fire is 1 to 3 months, the shortest only 14 days. For decades we have used river sand and yellow mud fillings to control and extinguish mine fires and played a big role. In the aspect of early prevention, we use the gas samples collected from coal in different stages of ignition, and analyze them with 2307 gas chromatograph to predict and forecast the gas. Significant results have also been achieved. However, the accuracy of forecasting and forecasting is mainly whether the gas production site has reached the site of ignition. Practice over the years has proved that the distance from the site of ignition
