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

Shockproof houses

One, technical field

A kind of security protection facility of industry to underground operators the present invention relates to dig up mine.

Two, background technology

Coal mine rock burst is that the down-hole country rock destroys suddenly, causes strenuous vibration and presses to manifest with a kind of ore deposit that a large amount of coal (rock) pieces are dished out, and be a kind of dynamic disaster of serious threat Safety of Coal Mine Production.Ji Zai bump occurs in Nanshi's tower good fortune colliery of Britain in 1738 the earliest.Now, in more than 20 countries and regions such as China, South Africa, Russia, Poland, the U.S., Germany, Japan all in the threat of pressing in varying degrees with being hit.All there is the bump disaster in mineral bureaus such as Beijing of China, Datong District, Fushun, Beipiao City, Yan Zhou, Zaozhuang, Xuzhou.Mining depth reaches the threat that the above most of mines of 500m all are subjected to bump to some extent.

In the bump generating process, cause large tracts of land roof fall, pucking, the tunnel roof and floor of work plane to close up,, then may produce injury, even cause death it if having the people to work in generation area.Studies show that behind the generation bump, the main position of injury to personnel is a brain, accounts for more than 90%; Next is the mechanical failure of chest, comprises that rib fractures, and accounts for 60%; And internal's damage mainly is lung, the heart, stomach etc., accounts for 19%; Secondly be fractureing of upper and lower limb again, also account for 19%.This mainly is that the vibration frequency of each organ of human body is consistent with the vibration frequency of bump, produces that resonance causes.And the oscillatory acceleration that bump produces makes human impact's object, causes resonance personnel's injures and deaths.Result of study shows, the energy that discharges in vibrations is greater than 10 ⁵Under the situation of J (1.7 grades of Richter scales), the vibration amplitude of oscillatory acceleration may from 2 to 100, even greater than 1000m/S ²

Press on the research direction on impact ground both at home and abroad, mainly concentrates on three aspects: the one, and the research of bump genesis mechanism; The 2nd, the research of bump hazard assessment, monitoring and prediction technology; The 3rd, the research of bump control measures.Yet because the bump genesis mechanism is very complicated, the bump problem remains a difficult problem that does not thoroughly solve as yet at present both at home and abroad, presses still on a lot of mine damaging impact ground and often takes place.Simultaneously, in existing bump hazard area operation place, there is not the safety prevention measure of special protecting against shock injury.

Three, summary of the invention

In order to reduce the casualties and the extent of injury of pressing harm to cause with being hit, the invention provides a kind of Shockproof houses, the space of hiding of safety is provided for the operating personnel in the bump zone, make the operating personnel in the bump generating process, when jolting collision, escape injury, thereby reduced the personal injury that brings because of bump significantly, reached the purpose of safety in production.

The technical solution used in the present invention is: adopt to reach deeply apart from face of land 500m or bump generation intensity at mine and reach Richter scale more than 1.5 grades the time, place, guard's property post in the bump zone, select ature of coal to construct Shockproof houses than benefit, its construction method is: the dark chamber of pick 2m, the supporting of " O " type of employing, canopy is apart from 0.7m, squeeze into the coal seam with the long anchor pole of 2m by the 0.7m spacing all around, the firm backboard of the tight edge of edge is installed the sponge vibration damper plate in the triplex row of the having stopped yoke, Shockproof houses, crust is wrapped with fire-retardant wind resistance tube cloth, the sponge vibration damper plate is fixed on the shed, and guarantees in the chamber the full section bag jail of obturaging, Shockproof houses is indoor to be installed more than the compressed air self-help of hiding personnel amount.

Because use anchor net " O " type canopy composite support, when bump took place, because supporting intensity is big in the Shockproof houses, it was less to be damaged, and can keep enough living spaces.Personnel jolt and when colliding, the vibration damper plate buffering are arranged, and can not injure.Both made the external world by the situation of shutoff under, also can utilize compressed-air system to wait for rescue safely.

Fig. 2 is a transverse sectional view of the present invention.

Five, the specific embodiment

In there is the danger of burst zone down-hole, fixed operation personnel operating location is arranged, build this Shockproof houses, at first tunnel the 2m tunnel, section is No.3.5, presses between 700mm, the full section of array pitch arranges resin half long anchoring rod 1, spreads and is just compiling wire lath; Press the 700mm canopy apart from back of the body No.3.5 (29U) " O " type canopy 3, three road clamps on the clinch, last four road iron lacing wires are fixed between canopy, the two groups Double Tops yoke 2 of stopping; Shop backboard 4 in the iron canopy, the use row of mixing greatly is tight, is fixed on the shed with wire rope, installs 1 * 2 * 0.2m sponge vibration damper plate 5 on the backboard; Adopt nylon rope 6 that every vibration damper plate is fixed on the shed, and guarantee in the chamber that the full section bag of obturaging is firm; Connect the compressed air self-help of establishing sufficient amount.Fixedly the number of seeing operating personnel can operation in Shockproof houses, and near other operating personnels can enter the protecting against shock layer and take refuge when bump danger takes place.

Claims

1, a kind of Shockproof houses, it is characterized in that: adopt to reach deeply at mine and reach Richter scale more than 1.5 grades the time apart from face of land 500m or bump generation intensity, place, guard's property post in the bump zone, select ature of coal to construct Shockproof houses than benefit, its construction method is: the dark chamber of pick 2m, adopt " O " type canopy (3) supporting, canopy is apart from 0.7m, squeeze into the coal seam with the long anchor pole of 2m (1) by the 0.7m spacing all around, the triplex row of having stopped yoke (2), the tight edge of edge firm backboard (4) in the Shockproof houses, install sponge vibration damper plate (5), crust is wrapped with fire-retardant wind resistance tube cloth, and vibration damper plate is fixed on the shed, with the bag jail of obturaging of full section in the chamber, Shockproof houses is indoor to be installed more than the compressed air self-help of hiding personnel amount.
