Problems solved by technology

However, due to the extremely complex mechanism of rock burst, the problem of rock burst is still a problem that has not been completely solved at home and abroad, and destructive rock burst still occurs frequently in many mines.
At the same time, there are no special safety protection measures to prevent impact damage in the existing workplaces in the rock burst hazard area

Embodiment Construction

[0010] In the area where there is a risk of impact in the underground, there are fixed operating places for operators. To build this anti-shock house, first excavate a 2m roadway with a section of No. Regular woven metal mesh; back No.3.5 (29U) "O" type shed 3 according to the shed distance of 700mm, three clips on the lap joint, four iron tie bars on the shed to fix, double-brake double-top wooden bars 2; Lay the backboard 4 in the iron shed, use a large mix to arrange it tightly, and fix it on the shed with a steel wire rope, and install a 1×2×0.2m sponge shock absorbing board 5 on the back board; use nylon rope 6 to fix each shock absorbing board On the shed, and ensure that the entire section of the chamber is tightly sealed and tightly packed; a sufficient number of compressed air is installed for self-rescue. The fixed number-checking operators can work in the anti-shock room, and other nearby workers can enter the anti-shock layer to take refuge in the event of rock bur...

Abstract

An impact-proof house is prepared by digging 2m depth of chamber at watching post in impact geopressure area, applying 'O' shape support, driving roofbolt of 2m into coal layer in 0.7 m of shedding distance, tieing up three rows of yokes, inlaying the backing plate and setting foam rubber shock absorption board in the house, wrapping flameproof tubular cloth on outer shell, fixing shock absorption plate on shed to enclose chamber completely and setting enough pressure air units for selfsaving.

Description

1. Technical field [0001] The invention relates to a safety protection facility for underground workers in the mining industry. 2. Background technology [0002] Coal mine rock burst is a kind of mine pressure that suddenly breaks down in the underground surrounding rock, causing violent vibration and accompanied by a large number of coal (rock) blocks thrown out. It is a dynamic disaster that seriously threatens the safe production of coal mines. The earliest recorded rock burst occurred in the South Stafford coal mine in England in 1738. Now, more than 20 countries and regions such as China, South Africa, Russia, Poland, the United States, Germany, and Japan are threatened by rock bursts to varying degrees. my country's Beijing, Datong, Fushun, Beipiao, Yanzhou, Zaozhuang, Xuzhou and other mining bureaus have rock burst disasters. Most mines whose mining depth reaches more than 500m are threatened by rock bursts to varying degrees. [0003] During the occurrence of rock...
