Embodiment 1

[0058] combine Figure 1 to Figure 5 As shown, the first embodiment provides an unmanned tunneling system for coal mine roadway, which includes: an accident isolation gate wall system, a remote intelligent control system for roadheaders, a remote control drilling and support system, an escape and transportation system, water and gas Drilling system, wireless communication, monitoring and personnel positioning system, the above six systems are coordinated with each other, and signal feedback control can be carried out according to needs.

[0059] In this embodiment, the accident isolation gate wall system is movably installed in the roadway, which isolates the roadway into a 100-meter danger relief area and a normal working area.

[0060] Preferably, the accident isolation wall system 1 includes: at least one self-moving disaster isolation gate wall 11; the self-moving disaster isolation gate wall 11 is arranged between the 100-meter danger relief area and the normal working ar...

Embodiment 2

[0131] The second embodiment provides a method for the coal mine roadway unmanned excavation system according to the first embodiment above, which includes the following steps:

[0132] The roadway is separated into a 100-meter danger relief area and a normal working area through the accident isolation gate wall system;

[0133] Among them, when the roadway is normally excavated, the accident isolation gate wall system is on standby, and the remote intelligent control system of the roadheader remotely controls the roadheader to carry out excavation operations in the 100-meter danger-relief area, and remotely controls the drilling and support system to remotely control the drilling rig The assembly performs support operations in the 100-meter danger-relief area, and the escape and transportation system assists in the transportation of materials. The water and gas drilling system can detect water and gas in the 100-meter-de-emergency relief area, and de-risk coal by drilling. To...

Abstract

The invention relates to the technical field of coal industry, in particular to an unmanned tunneling system and method of a coal mine roadway. The system comprises an accident isolation gate wall system, a remote intelligent tunneller control system, a remote control drilling and support system, an escape and transportation system, a water and gas drilling system and a wireless communications, monitoring and personnel positioning system. Therefore, urgent safety demand of the coal mine operation can be satisfied; effects of unmanned one-hundred-meter roadway danger elimination, catastrophic accident closure, and mechanical personnel evacuation are realized; and five kinds of disasters of water, fire, gas, coal dust and roof for tunneling of the roadway can be reduced or eliminated and thecoal mine casualties can be reduced by more than 50%. Moreover, the actual production demand can be satisfied; the tunneling speed is increased; the continuously tension situation of tunneling is changed; and the tunneling efficiency can be improved by 50% to 100%. The tunnel forming cost is lowered and the economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of the coal industry, in particular to an unmanned tunneling system and method for a coal mine roadway. Background technique [0002] With the development of microelectronics technology, computer technology and automation technology, high-efficiency mechatronics technology and complete sets of equipment have been rapidly promoted and applied in my country's coal industry, prompting a leap-forward change in traditional coal production. The level of equipment and the degree of automation have been further improved. At present, my country's coal industry has the ability to equip 10-million-ton open-pit coal mines and mine working faces with a daily output of 10,000 tons, and has built a number of large-scale coal mines with world-leading levels. However, there is still an important link in coal mine production at present, that is, the development of fully mechanized mining face still lags behind that of fully m...
