Application of Unit Type Over-Head Support in the Roadway Support of Comprehensive Release Working Face
In order to solve the problems of small intensity and high labour intensity of support by single hydraulic pillar with articulated roof beam and repeated support of roof plate by step-forward shifting type of over-advance support,Tangyang Coal Mine firstly used unit-type over-advance support in the roadway for over-advance support in the working face of 431 comprehensive workings.The installation of unit-type over-head support,anti-fall and anti-slip measures,quality standard of over-head support and safety technical measures in the process of use are introduced in detail.The use of over-head support not only reduces the labour intensity of the workers,but also realizes the safe and efficient production of the mine.
