Installation and Preparation
1. Prepare the rock drilling cavern, and the specifications of the cavern can be determined according to the drilling method.
2. Lead the gas and water pipelines, lighting lines, etc. to the vicinity of the working surface for use.
3. According to the requirements of the design of holes, erect the pillars firmly. The upper and lower ends of the pillar should be padded with wooden boards. After installing the horizontal shaft and the snap ring on the pillar according to a certain height and direction, use the hand winch to lift the equipment and fix it on the pillar according to the required angle, and then adjust the geological core drilling rig. hole direction.
Pre-job Inspection
1. Before starting work, it is necessary to carefully check whether the gas-water pipeline is firmly connected and whether there is any leakage of air or water.
2. Check whether the oiler is filled with oil.
3. Check whether the screws, nuts, joints, etc. of each part have been tightened, and whether the column is really firmly supported.
Drilling Procedure
When opening the hole, start the motor of the geological core drilling rig first, and then pull the push handle of the manipulator after the transfer is normal. Make it get the proper thrust, and then pull the handle that controls the impactor to the working position. After rock drilling, the water valve can be opened to maintain the proper ratio of the gas-water mixture. Carry out normal rock drilling work. When the advancing work moves the rod reel to collide with the drill, a drill rod is drilled. To stop the operation of the motor and the supply of air and water to the impactor, insert the fork into the drill pipe groove of the drill holder, make the motor reverse the slide plate and retreat, so that the joint is disconnected from the drill pipe, and then connect two drill pipes, press this step cycle continuous work.
