Abstract
The invention relates to an underground roadway plugging method and device. According to the underground roadway plugging method and device, the structure is simple, operation is convenient and safe, the workload of workers can be reduced, and the efficiency of workers can be improved. The underground roadway plugging method and device are characterized in that a frame of a plugging wall is built with steel rods, wood plates and a steel bar net, then filling bags are arranged in the frame, a pump station is arranged within a certain distance of the frame and used for stirring high-water-content materials, the filling bags are filled with filling materials through a pipeline after being well supported, and roadway plugging can be carried out after the filling materials are solidified. The method and the device are simple, effective and beneficial to efficient production of a mine.
Description
Technical field:
The method that the present invention relates to the closure of a kind of underworkings, uses a kind of simple mechanism water blockoff, prevents fires, hinders gas.
Background technology:
At present, coal mine roadway, during driving uses, needs because producing, and some tunnel needs discarded, for avoiding tunnel
The secondary harm brought, such as retention of excessive fluid, Gas Outburst or even spontaneous combustion of coal seam ignition etc., it is necessary to process tunnel.?
Straightforward procedure is by laneway plugging, intercepts one section and utilizes material tunneling boring to block, and isolation tunnel contacts with mine production system.
At present, the closure of underworkings is mainly cement injection closure, and closure framework mainly has two kinds, and one is in laneway plugging position
The upper wall of each block front and back, then closes space cement injection to this, and another kind is to replace building a wall with plank, sets up mould with plank
Son, constitutes and closes space then slip casting.Cement injection closure can block tunnel, but construction technology is complicated, and operability difficulty
Greatly, especially it may happen that plugging during slip casting, cost and the amount of labour are increased.
Summary of the invention:
In order to overcome the deficiency that existing technique can not facilitate workman to construct well and cost is bigger, the present invention provides one
Planting new method, this method can not only make the technique in closure tunnel simply, more can reduce mine production costs.
The technical solution adopted in the present invention is: installing pumping plant away from the tunnel rational position that need to block, facilitate haul and
Equipment is put, and at filling pumping plant stirring high-water material, (height of a kind of rapid condensation coagulates water material, ratio of mud 2:1, and comprcssive strength reaches
9MPa), utilize anchor pole, plank, filling bag to put up filling mould at block-up position simultaneously, pass through after casting resin stirring fully
Pipeline injects filling mould, and block wall is the formation of.
The present invention has the advantage that with good effect: equipment is simple, and labor strength is low, safe, economical, effectively.

Detailed description of the invention:
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
In Fig. 1, Fig. 2, building closure framework in laneway plugging position, substitute enclosing wall, the outside composition of closure framework is filled
Fill out barricade before and after bag, be made up of steel rod (2), plank (3), bar-mat reinforcement (4), then filling bag (5) is hung over closing space, fills
Top and the surrounding of filling out bag (5) have the part that can be used for fixing.Closure framework build process is: utilize air drill or other instruments
Play 1-2m deep drilling at closure front-and-back stop wall displacement every 1m, then firm rod (2) is inserted in boring, because of drift section diverse location
Height different, press desired height connection steel rod (2) at diverse location, after connecting, plank (3) tied up at the steel rod (2) put up
On, tie up lastblock every 800mm the most successively, depending on length is because of span length, then bar-mat reinforcement (4) is suspended on plank (3).
Wherein plank (3) uses veneer, width about 25mm, moderate length, conveniently binds；Bar-mat reinforcement (4) is by fine steel rib
Constituting, be commonly called as " reinforcing bar embankment ", use reinforcing rod to connect reinforcing rod by 10 × 20 eyelet weldings, " reinforcing bar embankment " length and width are regarding tunnel needs
Fixed, it is therefore an objective to the space of plank (4) and steel rod (2) to be blocked, in order to filling bag not external drum, prevent obturator in stowing operation from inhaling
Thermal expansion, causes the support of filling bag big, and generation is split up.After barricade is constructed, filling bag is sent into, each angle of filling bag is tied up
Surely arrive predetermined position, with good conditionsi hang up properly filling bag after and air blast inflation in filling bag so that filling bag is heaved to needs
Each corner of filling, improves the utilizing status of filling bag.Closure framying completes, followed by slip casting in filling bag.
In figure 3, during closure framework installs, Fig. 4 filling pumping plant starts spice, and first, second material is respectively with mining
Railway carriage feed, railway carriage stops in orbit, and in figure, filling pump (8) is placed on centre, first, second material be individually placed to first material agitator (10),
Second material agitator (11) stirs, and this equipment is positioned in stirring pool (12), and first, second material is watered the most by a certain percentage, stirs 3-5
Minute, work surface filling bag Zhi Haohou opens pressure-oil tank (9), and due to pressure effect, first, second serosity is respectively by pulp-absorbing pipe (7)
Sucking, the most filled pipeline (6) is transported to work surface, connects one between filling bag pipeline and first, second filling pipeline
Individual blender, makes two kinds of serosity reinject filling bag after being sufficiently mixed.After filling operation completes, with clean water pump and pipeline,
Making full use of the serosity in pipeline, prevent serosity plugging, cleaned water from injecting work surface, remaining water passes through rhone (13)
Being discharged in water channel, mixed serosity solidified about half an hour, within one day, i.e. can reach certain comprcssive strength, within seven days, reached maximum
Comprcssive strength.
