Mining deep hole grooving equipment and working method

Abstract

The invention discloses mining deep hole grooving equipment, and belongs to the field of mining equipment. The mining deep hole grooving equipment comprises a variable-diameter grooving saw blade (1), a transmission device (2), a power motor (3), a fixed support rod (4), a transmission pipeline (5) and a power control module (6), the power motor (3) transmits power to the variable-diameter grooving saw blade (1) through the transmission device (2), when the rotating speed of the variable-diameter grooving saw blade (1) is increased, the overall diameter of the variable-diameter grooving saw blade (1) is increased, the fixed support rod (4) fixes and supports the positions of all the parts, and the power control module (6) transmits power to the power motor (3) through the transmission pipeline (5) and can control starting, stopping and the rotating speed of the power motor (3). According to the mining deep hole grooving equipment and the working method, the whole set of equipment is simple in structure, low in cost and high in practicability, and the problem of deep hole directional grooving is well solved.

Description

technical field [0001] The invention relates to a mining deep hole slotting equipment, belonging to the field of mining equipment, in particular to a mining deep hole slotting equipment and a working method. Background technique [0002] In the process of mining, sometimes the roof above the goaf has a relatively complete structure, and it will not break naturally when the gob area is large. Support security. In order to solve this problem, it is necessary to artificially cut and break the roof above the goaf. The usual method now is to drill a row of relatively dense deep holes on the roof, so that a weak surface is formed on the roof of the rock formation, and then the roof is cut off by means of blasting or the like. After a lot of practice, we found that machining a groove in the deep hole has a very good effect on controlling the cutting direction and improving the breaking effect. However, due to space constraints, it is very difficult to perform directional slottin...

Problems solved by technology

[0003] In order to solve the problem of directional slotting in deep holes, the present invention discloses a mining deep hole slotting equipment, which includes a variable diameter slotting saw blade, a transmission device, a power motor, a fixed pole, a transmission pipeline, and a power control module. The power motor transmits the power to the variable diameter slotting saw blade through the transmission device. The overall diameter of the variable diameter slotting saw blade will increase when the rotation speed increases. The fixed pole fixes and supports the positions of each part. The power control module The power is transmitted to the power motor through the transmission line, and the start, stop and rotation speed of the power motor can be controlled
