Comprehensive mechanized coal mining technology
(I) working face layout
Comprehensive mechanized coal mining is referred to as "fully mechanized mining". Fully mechanized mining technology is characterized by coal drop, coal loading, transportation, support
Protection, goaf treatment and other processes are all mechanized. Fully mechanized mining uses self-moving supports to support the roof,
Solved the problem of manual operation of support and back-up and top-down, and realized the mechanization of support and goaf treatment,
It has the characteristics of low labor intensity, high output, high efficiency and good safety conditions.
The main equipment supporting the fully mechanized mining face is high-power double-drum shearer, high-power heavy-duty scraper conveyor.
machine, hydraulic support, transfer machine, belt conveyor and mobile substation, emulsion pump station, etc., working face
The equipment is arranged as shown in the figure.
