Abstract

The utility model relates to a filling air bag, in particular to a filling air bag for a mined out space, and belongs to the technical field of mining engineering. The filling air bag includes an air bag outer layer, an air bag inner layer and an inflating valve, wherein the outer part of the air bag inner layer is tightly covered with the air bag inner layer; the inflating valve penetrating the air bag outer layer is installed at the bottom of the air bag inner layer; the inflating valve consists of an inflating valve metal base and an inflating valve metal main body connector; the thickness of the air bag inner layer is 4-8 cm; and the thickness of the air bag outer layer is 2-5 cm. The utility model has the advantages that the filling air bag realizes the seamless filling, provides uniform supporting resistance, and is low in filling cost; the larger the volume of the mined out space is, the lower the cost can be; the filling procedure is simple and time-saving; the technical requirement is low; and the air pressure can be adjusted at any time.

Description

A kind of filling air bag that is used for the goaf

Technical field

The utility model relates to a kind of filling air bag, and particularly a kind of filling air bag that is used for the goaf belongs to the mining engineering technical field.

Background technology

The filling in goaf is the important step of metalliferous deposit underground mining.In order to ensure that underground mining work can be carried out safely smoothly and effectively to protect the face of land and building thereof, reduce permanent ore pillar, improve ore recovery rate as much as possible, these all need effectively be handled the goaf.Handle the effective method in goaf and exactly it is carried out filling.The basic demand of filling is can certain bearing capacity be provided to goaf country rock and top board, and the method that is adopted should be simple and easy to do, economical rationality.This just requires filling medium and material to possess certain intensity, and the rate of shrinking is little, wide material sources, and is cheap, on transportation range, also wants economical.

At present, both at home and abroad the goaf filling method of institute's ability usefulness mainly contains hydraulic silting, dry stowing, several kinds of forms such as consolidated fill, but all exist the filling cost height, and filling effect is bad, and the rate of shrinking is big, and the face of land still has shortcomings such as sedimentation, distortion.Even the high strength consolidated fill that filling effect is best can not effectively protect the face of land and building thereof, and filling cost is high especially.

Summary of the invention

The purpose of the utility model is to provide the filling air bag that is used for the goaf that a kind of filling expense is low, filling quality is high, filling procedure is simplified.

The technical scheme of the utility model is: a kind of filling air bag that is used for the goaf comprises air bag skin 3, air bag internal layer 4 and valve cock.Air bag skin 3 is tightly being covered in air bag internal layer 4 outsides, and the valve cock that passes air bag outer 3 is equipped with in air bag internal layer 4 bottoms.Valve cock is made up of valve cock metab 5 and valve cock metal master joint 6.The thickness of air bag internal layer 4 is 4~8 cm, and the thickness of air bag outer 3 is 2~5 cm.

Air bag internal layer 4 can be processed by basic butyl of peace or natural rubber material, has better elastic, ageing resistance, after the inflation, under the constraint of skin and country rock, huge supporting drag can be provided.Air bag outer 3 can be processed by the junked tire elastomeric material, and it act as, and for internal layer provides smooth, a smooth contact surface, the protection internal layer is not scratched by the country rock of projection, prevents that internal layer from being corroded, and can make stressed even.Valve cock is mainly used in inflation and venting.The shape of filling air bag is consistent with the goaf shape of institute's filling, and its ectonexine all adopts flexible material, at ordinary times foldable for storage and transportation.

During use, measure the geomery of required bashing earlier, the required maximum stress that offers country rock.Size according to the goaf produces shape goaf filling air bag of the same size then, and before this, reply goaf country rock 1 jet surface one deck concrete spray coating 2 increasing the planeness on surface, dead zone, and plays the effect of water-tight corrosion-proof to air bag.After treating that concrete spray coating 2 solidifies, just can the filling air bag be transported into the goaf, adjust balloon positions, its inflation back shape can be overlapped with the goaf.After balloon positions sets, with air compressor machine from valve cock inflation, up to air bag expand into the same with the dead zone size till.At this moment, shutoff is carried out in the tunnel 7 that links to each other with the dead zone, the shutoff partition wall adopts concrete material, and should reach enough thickness and intensity, and shutoff rear gasbag valve cock will stretch out the outer certain-length of partition wall, so that fill, exit.After treating that the shutoff partition wall has certain intensity, just can be to airbag aeration air pressure during to the required maximum supporting drag of country rock, air bag also formally plays the filling and support effect.

The beneficial effect of the utility model is: can realize seamless filling, the supporting drag that air bag provides is even, and the filling expense is low, and the dead zone volume is big more, and cost is low more, and filling procedure is simple, saves time, and technical requirements is low, and air pressure can be regulated etc. at any time.
