Description
Technical field
This utility model relates to coal face caving place Treatment process field, particularly relates to a kind of coal face caving place device for filling。
Background technology
Along with the fast development of colliery engineering, some high-yield and high-efficiency coal-faces producing million tons per year occur in succession；At work surface particularly high working face and the top-coal caving face of these high-yield and high-efficiencies, ore deposit pressure manifests acutely, and work surface wall caving, roof fall happen occasionally；Once there is roof fall accident in work surface, the caving place of formation can bring the risk of gas exceeding limit and gas explosion, and after roof fall, working surface hydraulic support loses and puts forth effort basis, will can't pass caving place, causes that work surface stops production for a long time；The mode processing work surface roof fall at present mainly adopts the way of framework grillage, and this processing mode exists shortcomings, is first that labor strength is big, it is necessary to gos deep into caving place and is stacked by one piece of block mine timber heap, until caving place top；Next to that working environment is dangerous, caving place is likely to have sillar to fall at any time, there is many potential safety hazards；In addition owing to working space is narrow and small, seriously govern speed of application。
Utility model content
The technical problems to be solved in the utility model is in that to be difficult to problem convenient, quick, safe handling for coal face caving place, provide a kind of coal face caving place device for filling, it can safely, quickly form Collapsed zone obturator structure, eliminate the risk that caving place gas exceeding limit even explodes, secure support is provided, it is simple to work surface is quickly through caving place for hydraulic support。
This utility model provides a kind of coal face caving place device for filling for solving above-mentioned technical problem, it is characterized in that: include filling pouch (1), Grouting Pipe (3), blast pipe (4), wherein Grouting Pipe (3) and blast pipe (4) are inserted in filling pouch (1)。
Further, described filling pouch (1) is the cube structure not leaked out, the processing of its bottom surface has two cuffs (6), for inserting Grouting Pipe (3) and blast pipe (4), at filling pouch (1) end face equipped with a pressure-relief valve (2), aerofluxus release can be automatically turned on when pressure reaches 0.2MPa。
Further, described Grouting Pipe (3) and blast pipe (4) are coating steel pipe, and caliber is 19mm, and bottom is all welded with straight-through (7), have at Grouting Pipe (3) upper end 1m～2m and penetrate slurry hole (5), and aperture is 5mm～8mm, and pitch-row is 100mm～150mm。
For achieving the above object, supporting construction (8) need to be built in filling pouch (1) bottom。
For achieving the above object, blast pipe (4) need to connect mine compressed air pipeline (10), utilizes blast to prop up filling pouch (1)。
For achieving the above object, Grouting Pipe (3) need to connect grouting pipeline (9), utilizes slurry consolidation body to form regeneration caving place structure。
As preferably, described caving place filler is the inorganic rapid hardening injecting paste material of biliquid, its two components mixing after can rapid solidification, 2h just has 2MPa～4MPa intensity。
Compared with prior art, of the present utility model have the following advantages and beneficial effect。
(1) safety is good, and labor intensity is little, simple to operate, and workman need not go deep into the deep operation of roof fall district, decreases the risk that falling rocks is hurted sb.'s feelings。
(2) support bag is convenient, directly utilizes mine pressure ventilation system and props up filling pouch (1), improves the adaptability of filling pouch and caving place shape, it is ensured that filling quality。
(3) speed of application is fast, coordinates the inorganic rapid hardening injecting paste material of biliquid, it is possible to quickly forms regeneration caving place entity structure, decreases the work surface off-time。
In sum, this apparatus structure is simple, and easy for installation, reasonable in design, security performance is good, speed of application is fast, it is possible to roof fall district, Reliable guarantee colliery filling quality, economic technology remarkable benefit。
Accompanying drawing explanation
Fig. 1 is this utility model one coal face caving place device for filling each several part schematic diagram。
In figure: 1-filling pouch, 2-pressure-relief valve, 3-Grouting Pipe, 4-blast pipe, 5-penetrates slurry hole, 6-cuff, and 7-leads directly to, 8-supporting construction, 9-grouting pipeline, 10-air line。
Detailed description of the invention
Below detailed description of the invention of the present utility model is made one to be discussed in detail, but be not used in restriction scope of the present utility model。
If Fig. 1 is a kind of coal face caving place device for filling, it is as follows that it is embodied as step。
Step 1, build a supporting construction (8) at caving place bottom plank and hydraulic prop, be used for supporting filling pouch (1)。
Step 2, filling pouch (1) it is placed in supporting construction (8) top and launches, Grouting Pipe (3) and blast pipe (4) are inserted filling pouch (1) from cuff (6), and with iron wire or rope, cuff (6) being tightened bundle jail。
Step 3, by blast pipe (4) connect mine compressed air pipeline (10), now filling pouch (1) will be opened gradually。
Step 4, Grouting Pipe (3) is stretched to caving place commanding elevation, and Grouting Pipe (3) and blast pipe (4) are fixed in supporting construction (8)。
Step 5, connection grouting pipeline (9), the inorganic rapid hardening injecting paste material of biliquid is irrigated to caving place, until filling whole filling pouch (1), after perfusion terminates by double-liquid grouting system, within two hours, just can have 2MPa～4MPa intensity, now can carry out being worked by caving place。
It it is more than an embodiment of the present utility model; but and unrestricted protection domain of the present utility model; every conversion utilizing this utility model description or accompanying drawing to carry out equivalent structure or be applied to other technologies field, is accordingly to be regarded as the protection domain of this utility model patent right。
