Fully-mechanized mining working face smooth trough advancing reinforcement support process and hydraulic support therefor

Abstract

The invention relates to an aggregate working face along-slot advanced reinforced support method and its special hydraulic support. The inventive method comprises: (1) a series of head hydraulic supports are mounted on the end of rail; several series of advanced reinforced hydraulic supports are laid in sequence along the propulsion direction, wherein, the first series laid in the same direction with the head supports while the left laid normally; (3) each hydraulic supports is moved along the guide rail in the bottom slide track of base box by the traction device; all the guide rails of hydraulic support connect end-to-end as a whole to make the support move straight; (3) when moving the support, the next series of hydraulic support offer cantilever beam for support in time to avoid top empty; (4) the lateral distances between posts of each series are increased as the channel for passengers and carrying material; (5) the said guard plates on the two sides of top beam support the top plate of two sides. Said invention need propulsion device, guide rail, cantilever beam, and side guard plate. It uses self-moving advanced reinforced support to reduce workload and labor strength, increase working efficiency, guard effect and safety.

Description

technical field [0001] The invention relates to the field of advance reinforced support along the groove of the coal mining working face, in particular to a fully mechanized mining working face advance reinforced support technology along the groove and a hydraulic support for the advance reinforced support along the groove of the track of the fully mechanized mining working face. Background technique [0002] The "Coal Mine Safety Regulations" stipulates that within 20m of the connection between all safety exits and the roadway in the coal mining face, the support must be strengthened; in the comprehensive mechanized coal mining face, the height of the roadway within this range shall not be lower than 1.8m. At present, most coal mines in my country require that the advance support distance of the track along the trough is not less than 60m in the operation regulations of the fully mechanized mining face. Among them, within 40m of the coal wall of the advance working face, an ...

Problems solved by technology

[0004] In order to overcome the deficiencies of the existing fully mechanized mining working face track along the trough advance strengthening support mode, the support workload and labor intensity of the workers are large, the work efficiency is low, and the deficiencies of unsafe back column topping, the present invention provides a fully mechanized mining face along the trough Advance strengthening support technology and hydraulic support, this process uses its combination of advance strengthening support hydraulic support and end hydraulic support to replace single hydraulic prop and metal cross beam, and carry out self-moving advanced support for track trough and end , reduce the support workload and labor intensity of on-site workers, improve work efficiency and support effect, and reduce unsafe factors
