Problems solved by technology

It can be seen that the layout of the ventilation system, transportation system, mining system, etc. is relatively complicated and scattered, and it is not convenient for centralized management. This traditional mining mode will lead to the inability to fully utilize its advantages in intelligent, automated, and unmanned working faces , which severely restricts the further development of safe and efficient mining technology in large mines, and cannot achieve the goal of unmanned safe and efficient mining of coal. It is imperative and urgent to innovate and adapt to the new mining mode of unmanned working face

Embodiment Construction

[0026] The present invention is described in detail below in conjunction with accompanying drawing:

[0027] Such as figure 1 ~ 4, the panel coal seam is divided into multiple unmanned working faces (there are 3 unmanned working faces shown in the figure), the long side of each unmanned working face is 1000 ~ 3000m, and the short side is 300 ~ 400m; The roadway of each unmanned working surface includes a level lane 1 and an opening 2; the said level lane 1 is located on a central axis of the unmanned working surface, parallel to the long side of the unmanned working surface and connected to the two long sides. The side distances are equal; the opening 2 is parallel to the short side of one side of the unmanned working surface and is equal to the length of the short side. The opening 1 divides the opening 2 into two symmetrical parts 2a and 2b; the opening 1 One end is vertically connected with the opening 2 in a T-shaped arrangement, and the other end of the level roadway 1 ...

Abstract

The invention discloses T-shaped roadway layout applicable to intelligent manless working faces. A roadway in each manless working face in each panel comprises a gateway and open-off cut, one end of each gateway is perpendicularly connected with the corresponding open-off cut, each open-off cut is divided into two symmetric portions in the left-right directions by the corresponding gateway, T-shaped roadways are formed, and the other end of each gateway is connected with a panel transport main roadway and a panel air return roadway. The T-shaped roadway layout has the advantages that the T-shaped roadway layout is applicable to exploiting the intelligent manless working faces of nearly horizontal coal seams and low-gas mines, roadway arrangement systems, transport systems, ventilation systems and the like of the manless working faces can be simplified, particularly, functions of section transport gateways and section air return gateways of the traditional U-shaped roadways are integrated in machine-track integrated large-span gateways, the section roadway tunneling and maintaining engineering quantities can be reduced to a great extent, and the safety and the management efficiencyof the manless working faces can be improved.

Description

technical field [0001] The invention relates to the field of mining engineering, in particular to a T-shaped roadway layout suitable for an intelligent unmanned working face. Background technique [0002] In recent years, with the continuous improvement of my country's comprehensive mechanized coal mining technology and equipment, unmanned working faces have become an important development direction and trend of my country's coal mining. The characteristics of the unmanned working surface are: Change workers from operators to inspectors, replace manual labor with equipment automation, and reduce the labor intensity of workers; The workers are liberated from the dangerous working face stope to the relatively safe section roadway monitoring center, and the equipment is remotely controlled in the monitoring center to improve the safety factor of workers. However, the advanced unmanned working face recovery system still adopts the traditional roadway layout and recovery meth...
