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] like 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 a cutout 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 is re...

Abstract

The invention discloses a T-shaped roadway layout suitable for intelligent unmanned working faces. Each roadway in the unmanned working face in the panel area includes a level road and a cut-out, and one end of the level road is connected vertically to the cut-out. , the cut eye is divided into two symmetrical parts by the level roadway, forming a T-shaped roadway, and the other end of the level roadway is connected with the panel transport alley and the panel return air alley respectively. The T-shaped roadway layout of the present invention is suitable for intelligent unmanned working face mining in near-horizontal coal seams and low gas mines. The level roadway integrates the functions of the section transportation level way and the section return air wayway of the traditional U-shaped roadway, which greatly reduces the amount of section roadway excavation and maintenance work, and improves the safety and management efficiency of the unmanned working face.

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...
