摘要
结合淮北矿业股份有限公司袁店一井煤矿1021工作面实际条件,对该矿支架支护阻力、超前支承压力及工作面巷道瓦斯浓度进行即时监测,由数据分析得到工作面回采时采场周期性的支承压力变化与瓦斯涌出关系,周期性的顶板垮落对瓦斯涌出的影响。
According to the practical condition of 1201 working face in Yuandian Coal Mine of Huaibei Mining Corporation,the support resistance, advance abutment pressure and gas density of working face are monitored timely. Through data analysis, the relationship be- tween stope cyclical abutment pressure change and gas emission in working face mining and the influence of roof caving on the gas emis- sion are achieved.
