Abstract：In shaft changed to drift construction of the ventilating shaft in Shilawusu Coal Mine ,we used its shaft sinking facilities ,and adopted the operation mold of drilling holes by drill rig ,loading rocks by explosion proof loader ,transporting rocks by explosion-proof rubber-tyred vehicle ,stockpil‐ing rocks in water nest of the shaft bottom ,seizing rocks by central rotated rock-seizing machine ,ele‐vating rocks by hoisting bucket ,these could achieve full-face excavation by one blasting and one bot‐tom clearing. And we adopted belt conveyor transporting material to bottom unloading type automatic discharge bucket ,hoisting bucket unloading material to explosion-proof rubber-tyred vehicle ,explo‐sion-proof rubber-tyred vehicle transporting material ,mixed type wet spraying machine spraying con‐crete ,these could reduce the links of transporting material ,and increase the speed of casting and transporting material. Thus ,we overcame the difficulties of underground narrow space ,could not store and stir a lot of stirring shotcrete material ,improve support efficiency.
