Technical Field
The invention relates to the technical field of mine filling, in particular to a cofferdam type filling retaining wall.
Background
In order to solve the difficult problems of surface rock movement, collapse, deep rock burst, rock burst and other geological disasters in the mining process, the filling mining method is increasingly applied, and the filling retaining wall is an essential process link in the filling mining method and is used for plugging a goaf outlet before goaf filling. The dead zone filling retaining wall is used as a key production link, the filling zone is isolated from the working zone, so that the problems of slurry leakage, slurry leakage and the like of the dead zone filling slurry are prevented, and the safety and reliability of the dead zone filling retaining wall are extremely important safety guarantee for underground workers, equipment and normal production. The filling retaining wall mainly has the following construction forms: brick structure retaining wall, wood structure retaining wall, concrete retaining wall, steel construction, etc.
The existing filling retaining wall has the following disadvantages:
1. the construction period is long. The comprehensive production capacity of the stope is low, and on the other hand, the dead zone cannot be filled in time, so that the dead zone collapses, the pillars are broken, and the safety and the recovery rate of resource recovery are affected.
2. The labor intensity is high. The operation space of the retaining wall construction position is narrow, and the mechanical operation is difficult to adopt. For example, when a concrete retaining wall is constructed, concrete is often manually stirred, the concrete is manually shoveled into a mold by using tools such as shovels, and when the height of the retaining wall exceeds a certain limit, the retaining wall is manually transported.
3. The top-contacting sealing effect is poor. The existing construction method is to reserve a manhole in the middle of the retaining wall, and after the retaining wall is constructed, workers enter the dead zone side of the retaining wall through the manhole and adopt sprayed concrete to fill the periphery of the retaining wall. The construction process of the technology is complex, the construction is carried out at the dead zone side, and the operation environment is extremely poor; and the sprayed concrete is poor in maintenance, is not tightly contacted with the rock surface, and cannot ensure the sealing effect, so that the slurry leakage cannot be effectively prevented.
The prior art (patent No. CN103397906B) discloses a grouting type filling retaining wall, a construction method, a vacant zone filling system and a filling method, wherein the retaining wall comprises a front bearing wall, a rear bearing wall and a slurry storage bag positioned between the front bearing wall and the rear bearing wall; the rear bearing wall is positioned on the side of the empty area to be filled, the front bearing wall is positioned on the opposite side of the empty area to be filled, and the front bearing wall and the rear bearing wall comprise a protective net and a support frame; the top of the pulp storage bag is hung on a roadway top plate, and a filling hole and an overflow hole are arranged in advance on the front side of the pulp storage bag. After the front bearing wall, the rear bearing wall and the slurry storage bag are erected, filling slurry is filled into the bag, namely a 'filling body plug' is poured, and the aim of effectively plugging the stope roadway of the to-be-filled goaf can be achieved.
The slip casting type filling retaining wall is poor in anti-overturning performance and anti-shearing capability of a vertical face filling retaining wall, in order to solve the problem, the thickness of the retaining wall is often required to be filled, the thick filling retaining wall consumes a large amount of filling slurry, the construction cost is high, the construction period, the filling slurry solidification time and the maintenance period of the thick filling retaining wall all need to spend a large amount of time, and the periodic requirement of filling mining cannot be met.
