摘要
本文分析了无预掘煤巷前进式工作面，尤其是下隅角存在突出危险性，并结合秋湖煤矿的具体情况，提出了利用前进式工作面支承应力的充分前移来控制煤与瓦斯突出技术方法。通过试验研究，得出了秋湖煤矿试验工作面控制煤与瓦斯突出的有效合理作业循环方式，对该矿防治煤与瓦斯突出具有十分重要的应用价值。图４、参２。
The paper analyses the danger in advancing face that there is no prepared gate road, especially in underneath corner. According to the actual condition of Qiuhu mine, we provide the technical methods to be applied the enough converyer advancing of the abutment inadvancing face to control burst of coal and gas. Having carried out a lot of experiments, We puts forward a effective rational working circulation way to control burst of coal and gas in experiment value to be applied to prevention of coal and gas burst. 4figs., 2refs .
