Description
Technical field
The present invention relates to the filling of a kind of colliery and use system, relate in particular to a kind of hauling pipe formula filling system that is applicable to the girdle breaking roof.
Background technology
The girdle coalfield is very common in the colliery of China, just belongs to typical thin basement rock, thick alluvium coal seam like bog-head coal field, north, the Yellow River.Its girdle mainly refers to seven, ten layers of coal, and bedrock thickness is generally 30～40 meters, and thickness of surface soil is generally about 200m, and coal seam thickness is merely about 1.2m; The inclination angle is little, and gas is high, and water yield is big, and top board is broken unusually; The face of land is alluvial plain, the Yellow River north, and physical features is smooth in the field with "nine squares" in, and phreatic table is below the face of land about 1.5 meters, and exploitation afterwards subsidence coefficient reaches 0.82; Above ground structure is than comparatively dense, and underground mining is bigger to the face of land and building influence, and ton coal profit is merely 50 yuan/ton.Several kinds of filling methods of using at present; Like fall behind paste body filling, the efficient frame cash filling, high water filling etc., because filling cost is higher relatively, the paste body filling cost falls the cash filling cost at 100 yuan/ton behind 120 yuan/ton, efficient frame; 160 yuan/ton of high water filling costs, ore deposit side can not accept.
Summary of the invention
The present invention is directed to the girdle special geological condition; Directly the top is with adopting with emitting and unusual fragmentation; Old top presses step pitch about 12～14m; There is the time and the space of certain movement on promptly old top (basic top), design a kind of " hauling pipe " formula filling process system that utilizes the direct top of fragmentation behind the seam mining as the leak stopping wall.This system can form casting resin to the spoil that driving produces through broken back and a certain amount of flyash, cement, utilizes batch (-type) concrete pump and pipeline pack to the goaf, reaches the purpose of control rock stratum depression.
Its technical solution is:
A kind of girdle hauling pipe formula filling system; Comprise and be arranged in the filling person in charge, high-order filling steel pipe, high-pressure rubber pipe and Duo Gen filling pipe in the work plane crossheading; Said filling is responsible for and is provided with reducing tee, and said high-pressure rubber pipe is connected to said filling through said reducing tee and is responsible for; Said filling pipe is connected in parallel on the said high-pressure rubber pipe, and said filling pipe is fixedly connected on the working surface hydraulic support between goaf and the coal seam, and with moving of hydraulic support, the filling mouth of said filling pipe extend in the goaf; One end of said high-order filling steel pipe is connected said filling and is responsible for, and the other end passes lane group filling wall and extend in the goaf, and the height of the filling mouth of said high-order filling steel pipe is higher than the height of said filling pipe filling mouth.
The quantity of preferred said filling pipe is identical with the quantity of working surface hydraulic support, and a filling pipe is set on every hydraulic support.
Preferred every filling pipe is provided with valve and flow, pressure sensor.
Preferred said filling is responsible for and is provided with valve and flow, pressure sensor.
The filling mouth of preferred said high-order filling steel pipe is pressed close to the gob floor setting.
The diameter of preferred said high-order filling steel pipe is greater than the diameter of filling pipe.
The invention has the beneficial effects as follows: under the situation that need not transform support and structure leak stopping wall,, reduced the motion of overlying rock, reached the purpose of control subsidence directly to goaf filling; Filling pipe is directly followed support with the propelling of work plane and is moved forward, and has improved pack effectiveness; Through high-order Grouting Pipe, directly bashing roof collapse band makes caving zone and broken overlying rock bond together through slip casting, has reduced the pressure of overlying rock to lane group filling wall, has protected lane group filling wall.
Description of drawings
Accompanying drawing 1 is the structural representation of girdle hauling pipe formula filling system according to the invention.
The specific embodiment
Referring to accompanying drawing 1, a kind of girdle hauling pipe formula filling system comprises being arranged in the filling person in charge, high-order filling steel pipe, high-pressure rubber pipe and Duo Gen filling pipe in the work plane crossheading; Filling is responsible for and high-order filling steel pipe can be selected common steel tube for use, and diameter is freely chosen according to the underground filling needs, and the withstand voltage properties of high-pressure rubber pipe wants to satisfy the needs of stowing pressure; Filling pipe selects for use the common filling floral tube in down-hole to get final product; Middle part on filling is responsible for is provided with reducing tee, and high-pressure rubber pipe is connected to filling through reducing tee and is responsible for, and many filling pipes are connected in parallel on the high-pressure rubber pipe; Filling pipe is fixedly connected on the working surface hydraulic support between goaf and the coal seam simultaneously; With moving of hydraulic support, form " hauling pipe formula " filling system, the filling mouth of filling pipe (floral tube end) extend in the goaf; The quantity of preferred filling pipe is identical with the quantity of working surface hydraulic support, promptly on every hydraulic support a filling pipe is set; One end of high-order filling steel pipe is connected said filling and is responsible for; The other end, just filling mouth end passes lane group filling wall and extend in the goaf, and the height of the filling mouth of high-order filling steel pipe will be higher than the height of filling pipe filling mouth; Preferred its is close to the goaf top plate setting; That is to say as much as possible near goaf top plate,, the diameter of the diameter of high-order filling steel pipe greater than filling pipe can be set for guaranteeing the filling effect of top board.
For detecting charging quantity and filling velocity, can on the every filling pipe and the filling person in charge, flow, pressure sensor be set, through the control system; Like monitoring of tools filling situations such as computer, PLC; Simultaneously can also on every filling pipe and the filling person in charge, valve be set, when needs stopped the filling in somewhere, the valve of closing on the filling pipe of relevant position got final product; When needs stop whole filling, then close the valve that filling is responsible for.
In stowing operation; Along with the passing of coal-face, open each road valve, filling pipe carries out filling to the goaf; The direct bashing roof collapse of high-order filling steel pipe of while band; Caving zone and broken overlying rock are bonded together through slip casting, reduced the pressure of overlying rock, protected lane group filling wall lane group filling wall; When work plane moved forward, hydraulic support moved forward with moving of coal-face, and the filling pipe on the hydraulic support also moves forward thereupon, at this moment, can artificially move high-order filling steel pipe, and it is adjusted to correct position, began the stowing operation of next stage.
The above; Be merely the preferable specific embodiment of patent of the present invention; But the protection domain of patent of the present invention is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that patent of the present invention discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of patent of the present invention.
