Problems solved by technology

[0004] 1. The tunnel excavation section is small: the excavation section is generally 15M 2 Left and right, when the height of the roadway exceeds 2 meters, scaffolding must be set up to carry out the construction of the roof anchor rod and anchor cable
[0005] 2. Non-mechanized operations. The construction of mine roof bolts and cables using continuous mining and continuous excavation technology has basically realized mechanization. All the excavation processes of bolt and anchor cable construction are carried out by hand-held pneumatic drills. The thrust of the drilling comes from the human arm and arm, and the labor intensity of the workers is high.
Since the construction of the anchor bolts and cables mainly relies on manpower, the construction quality of the anchor bolts and cables cannot be guaranteed fundamentally.
[0006] 3. The construction speed is slow, and it takes a lot of time to build and dismantle scaffolding when the construction section exceeds 2 meters
[0007] 4. Low efficiency: Due to the large number of drilling holes and the large number of construction workers, the operation efficiency is low
[0008] 5. Low safety factor: construction workers work alternately at high altitude, and the working safety environment is poor
[0011] 2. It takes a long time to advance and retreat the machine, and the auxiliary workload is large
Due to the excavation construction, two drilling rigs need to be driven into or out of the excavation face in sequence, coupled with the dragging of the cable, the time is long and the auxiliary workload is large
[0012] 3. Poor adaptability to complex geological conditions
In case of complex geological conditions such as faults, high gas areas, and high water content areas, the drilling rig cannot complete the construction of gas prediction holes, gas discharge holes, geological detection holes, and vibration blastholes
[0013] 4. The construction of roof anchor rod and anchor cable can not reach zero lag, which is unfavorable to the control of road side
[0014] 5. The workload of the roof bolt and anchor cable construction does not match, the workload of the top drill is large, and the workload of the side drill is small, which affects the support time and causes personnel to work idle
[0015] 6. The construction workers are working alternately at high altitude, and the working safety environment is poor
[0016] 7. There are a lot of people, two drilling rigs need to be equipped with 8 people
