煤和瓦斯突出预测预报是防治煤和瓦斯突出的一个重要方面。我们在有严重煤和瓦斯突出的河南省安阳矿务局龙山煤矿开展了煤和瓦斯突出预测预报的试验研究工作,利用煤的瓦斯放散初速度ΔP、煤的坚固性系数f、煤的突出危险性综合指标 K、煤的筛分指数 C、煤层揉皱系数 R、掘进工作面绝对瓦斯量 Q_绝等项参数,结合煤和瓦斯突出与地质构造的关系,进行了煤和瓦斯突出的试
Coal and gas outburst forecasting is an important aspect of coal and gas outburst prevention. We conducted a pilot study on prediction of coal and gas outburst in Longshan Mine of Anyang Mining Bureau with serious coal and gas outburst. Utilizing the initial velocity of coal gas discharge ΔP, the solidity coefficient of coal f, the prominent danger of coal Comprehensive index K, sieving index C of coal, crumple coefficient R of coal seam, Q_ absolute parameters of the absolute gas amount of heading face, and according to the relationship between coal and gas outburst and geological structure, the coal and gas outburst test
