Integrated suspension device for retaining a lane for next sublevel

Abstract

The invention relates to a gob-site entry retaining comprehensive support device, which effectively solves the problems not solved in the prior art that how mechanized formwork erection and whole support are carried out, and realizes difficult problem that filling and coal-mining production are carried out at the same time. The technical key points of the device are as follows: a roadway advancing and retaining support is arranged in a transportation roadway or a return airway; a roadway filling back formwork support, a roadway side filling formwork support and a set of working face hydraulic supports are arranged parallelly in sequence along a roadway; and all supports are vertically connected along the running direction of a transporter; the roadway side filling back formwork support, the roadway side filling formwork support which is arranged on the left of the roadway side filling back formwork support, and an adjustable hydraulic formwork which is arranged on the right of the roadway side filling back formwork support to surround a filling mould cavity which forms a gob-site entry retaining and filling wall. The device has the advantage that the device is favorable for mining a no-coal pillar, is safe and convenient to operate, and is strong in adaptability, can form an insulating gob area in the roadway side and a shield concrete filling wall which is solidified and hardened into a regular wall body, and can shield and match a working face transporter, a coal mining machine and a formwork support to perform normal coal-mining production.

Description

technical field [0001] The invention relates to a support device for back mining coal mining in a coal seam mining face, in particular, it is suitable for any form of support operations in the mining area such as retaining roadways along the gob and filling beside the roadway, and is used in the roadway of the goaf. A comprehensive support device for gob-side entry retaining is constructed on one side of the filling body. In the area where the filling body needs to be constructed, it can not only form an isolated goaf, cover the concrete filling wall to solidify and harden into a regular wall, but also cover and cooperate with the working face conveyor, coal shearer and common working face hydraulic support , formwork support, etc. for normal coal mining production. It belongs to the field of coal mining machinery manufacturing. Background technique [0002] Since the 1980s, my country began to explore and research coal mining methods without coal pillars (also known as go...

AI Technical Summary

Problems solved by technology

This is currently the most popular method of filling and supporting gob-side entry retaining in the world, but this method mainly states the materials and structure of the wall, and does not involve how to use the mechanized operation in the filling process. Filling templates and support devices

[0003] To sum up, there are currently no reports on the complete gob-side entry retaining filling support method and equipment to realize the solidification of paste concrete in the mechanized filling formwork and the implementation of mechanized support methods for the filling area
