Installation and preparation of drilling rig

1. Prepare the rock drilling cavern, and its specification can be determined according to the drilling method. Generally, when drilling horizontal holes, the cavern height is 2. 6-2。 8m. When chiseling upward hole, downward hole or inclined hole, the width of the cavern is 2. 5 meters, height 2. 8-3 meters.

2. Lead the gas and water pipelines, lighting lines, etc. to the vicinity of the working face for use.

3. The column shall be erected firmly according to the design requirements. The upper and lower ends of the strut should be planked with wooden boards. The horizontal axis and the clasp are mounted on the pillars in a certain height and direction. The hand winch is used to lift the machine and fix it on the pillar according to the required angle, and then adjust the hole direction of the drilling machine. When drilling upward holes, use two horizontal axes in parallel; When drilling horizontal and holes, generally only one horizontal shaft is used. When drilling other holes, * * * uses three horizontal shafts to connect two auxiliary horizontal shafts, one end is fixed on the sliding frame and the other end is connected to the strut, and the sliding frame is firmly erected together with the main horizontal shaft. After the machine position is aligned, tighten the bolts of the horizontal shaft and snap ring.
