摘　　要：在我国高瓦斯突出矿井机掘工作面，因受瓦斯超限和煤与瓦斯突出等不安全因素的影响，机掘速度受到严重制约。煤科总院重庆分院研制的与掘进机配套的机载式全液压防突钻机，利用其特有的功能，向工作面前方打瓦斯排放钻孔，释放突出潜能，实现了安全快速掘进。In mechanized heading faces in China’s highly gassy and outburst-prone mines,the advance rate of mechanized drivage is severely restricted by some unsafe factors such as disallowed methane level and outburst of gas and coal.Developed by Chongqing Branch,CCRI,a fully hydraulic drill mounted on heading machine,forming a complete set with the heading machine,can drill boreholes for gas drainage in the front of heading face by its special functions so as to release the potential of outburst and realize rapid drivage safely.
