Horizontal transport haulageway for mid-deep and deep mining

Abstract

The invention discloses a horizontal transport haulageway for mid-deep and deep mining, which comprises a haulage level hanging wall haulageway, a footwall haulageway, and an annular haulageway formed by a haulage level transverse drift roadway. The horizontal transport haulageway for mid-deep and deep mining is characterized in that a pressure relief line is made from an angle part of an air return horizontal mining roadway lying side to the transportable horizontal surface; an 90-degree included angle is formed between the pressure relief line and the transportable horizontal surface; an upper side of the hanging wall haulageway is arranged from a boundary of a footwall of an ore body to the outside of the pressure relief line. Through the manner, a position of the horizontal transport haulageway is confirmed, the additional force action of a wedge-shaped pressure body is avoided, the haulageway digging cost is greatly saved, the service life of a main transport haulageway is prolonged, the working conditions of workers is improved, and the recovery rate of ores is improved.

Description

technical field [0001] The invention belongs to the technical field of underground mining, in particular to a horizontal transport roadway for middle-deep and deep mining. Background technique [0002] Underground mining is mainly technology such as development, mining, mining and ore extraction, and mining methods are divided into three categories: open-field mining method, filling mining method and caving mining method according to the method of ground pressure maintenance. [0003] For steeply inclined ore bodies, no matter what mining method is adopted, the ore body is divided into several stages from top to bottom for mining. Between each stage, that is, at each level, from the wellhead to the ore body, the stone gates leading to the ore veins, the upper and lower wall transportation roadways, and the vein-piercing roadways are arranged. These horizontal transportation roadways are part of the roadway development. The level of the roadway in the upper part of a stage i...

AI Technical Summary

Problems solved by technology

[0011] The second is that the upper transport roadway has been under pressure and damage. If the maintenance is not timely, it may not be used and become a waste project. In this way, a roadway must be redesigned and constructed to replace it;

[0012] The third is that the maintenance of the roadway is very difficult. Even if the roadway is technically supported in various ways, it still cannot prevent the continuous deformation and damage of the roadway;

[0013] Fourth, due to the existence of deep ground pressure and the additional force of the wedge-shaped body on the upper wall, there are potential safety hazards in the use of this roadway, and it is necessary to be vigilant at all times for the occurrence of rockburst, that is, the phenomenon of rockburst;

[0014] Fifth, a lot of manpower, material and financial resources need to be invested in roadway maintenance;

[0015] Sixth, during roadway maintenance, the roadway cannot be used, which will seriously affect production
