Background technology
After mine generation water bursting, in order to ensure this top, ore deposit production system and the safety in adjacent ore deposit, flood water level under often adopting strong row's means control well, now under dynamic regimen condition, to be carried out stifled water. Generally, the method of tunnel dynamic water sealing is by boring stake aggregate on ground, aggregate is generally sand, rice stone and rubble, aggregate is relied on to build the section of blocking water in tunnel, progressively reduce the water amount in tunnel, finally injecting cement grout thoroughly to be blocked in tunnel, under hydrostatic condition, the water inrush channel in formation carries out grouting treatment more afterwards.
The control that aggregate is outflowed by current mine dynamic water sealing is poor, the aggregate being filled in tunnel in water-blocking in mine, under the continuous erosion of dynamic water is moved, some defines the wall or enter in water inrush channel of blocking water, effectively play the effect of stifled water, flow in coal mine excavation system with outside prominent water when some is then in damming. The a large amount of outflows of aggregate outside the section of blocking water of tunnel are the great problems of in stopping up water work, the invalid outflow of aggregate means that the material of waste is many on the one hand, that speedily carries out rescue work is long in time limit, the cost height of engineering, stifled water terminates to need to do a large amount of aggregate removing work during rear mine recovery is produced on the other hand, the time that seriously delayed mine recovery is produced, the mine majority of domestic employing dynamic water sealing has the experience of this respect.
In the face of a large amount of outflows of aggregate, existing control method one builds chemical pulp wall, and one is that heap builds Coal sack wall. The concrete grammar building chemical pulp wall is urgent construction twice concrete walls in away from the high absolute altitude tunnel of projective water point, and then injecting in the middle of two bodies of wall can the chemical pulp of rapid solidification. Requiring when building wall to bury heavy caliber water discharge pipe in advance and install gate valve, stifled water can control prominent discharge in speedily carrying out rescue work, and reduces the outflow of aggregate to reduce the method for dynamic water flow velocity, if desired can valve-off still pool. It is pile up, in water tunnel excessively, the woven bag that coal block, spoil are housed that heap builds the concrete grammar of Coal sack wall, and neat code forms well one waterwall, stops aggregate diffusion with body of wall. The shortcoming that above-mentioned chemical pulp wall method exists is: the time 1, building body of wall is longer, it is necessary to the time of several days, therefore when the prominent water yield is bigger, speedily carries out rescue work in critical condition to remove in people and has no time to attend to other, it is very difficult to have the enough time to build wall; 2, risky in the process closing the prominent discharge of body of wall valve minimizing: because of wall system fast construction, without compression tests, therefore valve-off hydraulic pressure rising back wall has the danger washed away by hydraulic pressure completely. Coal sack wall also has similar shortcoming:: the time 1, built is long, it is necessary to several classes'es (8 hours being a class); 2, body of wall easy distortion and collapsing under the washing away of tunnel current, makes the effect that control aggregate outflows have a greatly reduced quality.
