在急傾斜煤层的开采中,为实现高生产率的新工艺流程,需要有一种按准确方向沿煤层移动的可控制的钻巷机。下面介绍这种可控制的钻巷机的设计基础。钻巷机在垂直平面内借助于程序闭合的主令控制按规定的轨迹进行移动,或者采用 In the mining of steep coal seams, in order to achieve new processes with high productivity, there is a need for a controlled drill lane that moves in the right direction along the coal seam. The following describes the design basis of this controllable machine. Drilling alley in the vertical plane with the program closed master order to control the movement of the track, or use
