Azimuth, drilling angle, each hole terminal to center it is flat away from, coal seam puppet inclination angle, drilling it is flat hang down away from, the center that drills it is high
Parameter, azimuth, inclination angle and the hole depth of design drilling according to needed for being drawn above-mentioned functional relation.This method not only considers
The pseudo- inclination angle in coal seam, and accurate calculating has been carried out to the azimuth, inclination angle and hole depth of drilling, while set before reducing
Cumbersome process is counted, improves the operating efficiency of drilling design, adds the degree of controllability and one-tenth porosity of drilling, is reduced because of control
The not in place and drilling constructed again, greatlys save cost input.
If each exposed coal drilling, by former drilling design, controls drilling not in place to have 1-20 by 45 calculating；
One hole hole depth is calculated by 60m, and plus artificial and fee of material, cost is at 800 yuan or so；Complement once needs 800~16000 yuan of cost
Left and right.
Drilled using the exposed coal and passing fault of drilling design precision programming, control range and precision are high, greatly reduce
The presence of uncontrollable factor, reduce the incidence of accident.
