摘要

In mechanized heading faces in China's highly gassy and outburst - prone mines, the advance rate of mechanized drivage is severely restricterd by some unsafe factors such as disallowed methane level and outburst of gas and coal. Developed by Chongqing Branch, CCRI, a fully hydraulic drill is mounted on heading maching, forming a complete set with the heading machine, whcih cna dill 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.
