Problems solved by technology

This kind of construction technology is based on the premise of crowd tactics and endless holidays. However, with the relative reduction of personnel, the labor force is relatively insufficient and the regular circulation is difficult to maintain. The single entry level of rock roads cannot be guaranteed. Back road battery car transportation has disadvantages such as low excavation efficiency, large number of post personnel, and high labor intensity of employees, which seriously restricts the single entry level of large-section rock roadway excavation

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] A mine rock operation process, comprising the following process steps:

[0017] 1) Drilling process: hydraulic drilling rigs are used for drilling; through innovative practice, hydraulic drilling rigs are used to increase the blasting drilling speed, give full play to the advantages of equipment, shorten the absolute time occupied by drilling, and improve drilling efficiency. The two parts of the hydraulic drilling rig drill at the same time, the average working time for a single hole is 70s, and the drilling of the full section (taking 62 blastholes as an example) does not exceed 80 minutes (the time spent includes drilling, adjusting the drilling arm, moving the machine back and forth, etc. ), compared with three pneumatic drills drilling at the same time for 140 minutes, the work efficiency is improved by 43%.

[0018] 2) Blasting ...

Abstract

The invention discloses a mine rock work technology which comprises the following steps of 1) drilling in which a hydraulic driving drill carriage carries out drilling; 2) explosion in which medium-length holes are used for explosion and a double slotting plus reverse charging explosion method is implemented; 3) rock shipment in which an excavation type loader is used to remove waste rocks, airborne hydraulic forepoling temporary support is used, the temporary support efficiency is improved, shipment of waste rock removal is continuous, waste rock removing time is shortened, a hydraulic forepoling system is installed in an upper platform of the excavation type loader, and the forepoling temporary support can move forwards, elevate and back off automatically; and 4) ditching in which a tunnel restorer digs rough ditches, and artificial excavation is replaced. According to the mine rock work technology, the drilling manner is improved by taking high efficiency and rapid excavation as a target, and the construction speed is improved; and the explosion technology is optimized, the explosion efficiency is improved, the rock shipping system is improved, continuous transport is realized,and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of coal mine underground roadway development operations, in particular to a mine rock operation process. Background technique [0002] At present, the rock roadway excavation technology at home and abroad is mainly based on blasting excavation technology and fully mechanized excavation technology. Compared with blasting construction, the fully mechanized excavation technology is still not mature enough, especially in my country's rock roadway mechanized excavation machines, which have the problems of high energy consumption, high failure rate, low efficiency, and poor adaptability, and the application effect is not ideal, which is still in the experimental and exploration stage. . The length of the rock roadways excavated in my country every year is as high as thousands of kilometers, of which the drilling and blasting method accounts for more than 90%. However, the single entry level of the traditional blasting cons...
