Abstract
The invention belongs to the field of mining and relates to a sectional filling method of an old lane. The sectional filling method of the old lane comprises the following steps: A) drawing a stratigraphic relation layout diagram of a working face and the old lane and marking the positions of the old lane, the working face and other lanes, the shoring way of the old lane and other parameters in a detailed manner; B) selecting fly ash or slag ash and other radiation-free materials with lower sulfur content as filling materials, screening the filling materials, then bagging and putting into a well; C) filling the old lane in the position which is ahead of the working face 50m at least, and performing stage-by-stage step-by-step filling on the old lane from the working face to a terminal mining line; and D) performing sectional filling construction. The method has the beneficial effects that the sectional filling is adopted, the filling efficiency is high, the recovery and the filling do not affect each other, the filling cost is low, and the consumed time is short, thereby not only solving the problems of ground pressure occurrence of the working face, roof caving, subsidence of a support, loss of coal resources and the like during the recovery period, but also avoiding the defects of waste of the filling materials and long consumed time for filling.
Description
Technical field
The invention belongs to field of mining, relate to a kind of old working sublevel fill stoping method.
Background technology
For the special mining face of crossing old working in the progradation; Because old working is various at layer position, the arrangement of work plane; Stoping period can cause work plane ground to press to manifest, the advance of the face is sunk, influenced in roof fall, support, cause problem such as coal resources loss, and traditional whole fill method exists filling cost height, length consuming time, the easy shortcoming that normal propelling is impacted.
Summary of the invention
The present invention provides a kind of old working sublevel fill stoping method in order to remedy the deficiency of prior art, not only guarantees filling effect but also avoid the casting resin waste, reduces loading time, effectively solves the contradiction between the normal propelling of filling and work plane.
The present invention realizes through following technical scheme:
Old working sublevel fill stoping method of the present invention, its special character is: may further comprise the steps:
A, drawing face old working layer position relationship figure mark position, old working support pattern and other parameter in old working and work plane and other tunnel in detail;
Lower, the cold materials of sulfur content such as B, selection flyash or slag ash screen the back pack to casting resin to go into the well as casting resin;
C, work plane 50m carries out filling to old working at least in advance, to carrying out stage by stage progressively filling from work plane to the old working that stops adopting line;
D, carry out sublevel fill stoping construction.
Old working sublevel fill stoping method of the present invention, among the step D,
(1) is in this layer and the old working parallel with work plane; Take intensive sublevel fill stoping mode; Be to leave not filling section between per two fillings buttress in the old working; Distance between per two fillings buttress is not more than span length; During filling; Casting resin is filled to apart from old working top board 0.7m-1.0m, stays airspace;
(2) be in the old working and the top layer old working of this layer and or oblique vertical with work plane; Take general sublevel fill stoping mode; Be to leave not filling section between per two fillings buttress; Distance between per two fillings buttress; When the old working support pattern falls behind, face pressure is big, when existing specific positions such as grade separation, usual friendship, oblique to concern with other tunnel; Dwindle the distance between the filling buttress, on the contrary the distance of widening;
(3) part bottom old working is that tunnel part is in the work plane, part is in the work plane bottom, during filling, in old working, demarcates work plane coal cutting base plate line earlier, and 0.4m marks fill line under the base plate line then, whole fill under the fill line.
The invention has the beneficial effects as follows; According to old working top board situation and support pattern; Arrangement and length; Face pressure; Adopt sublevel fill stoping with the factors such as position relation in other tunnel; There is not filling section in the old working (stowboard); Through adopting flyash; Casting resin sublevel fill stopings such as slag ash; Pack effectiveness is high; Back production and filling are independent of each other; Filling cost is low; Weak point consuming time; Both having solved stoping period work plane ground pressure manifests; Roof fall; Support sink and problem such as coal resources loss; The casting resin waste of having avoided traditional filling method to cause again; The shortcoming of filling length consuming time has reached quick filling; Do not influence the purpose of working face extraction.
Description of drawings
Accompanying drawing is a structural representation of the present invention.Fig. 1 is in this layer and the old working parallel with work plane, and Fig. 2 is old working and the top layer old working that is in this layer and or oblique vertical with work plane, and Fig. 3 is the bottom old working, and arrow is represented advance of the face direction among Fig. 3.
Among the figure, 1 pack portion, 2 old workings, 3 work planes.
The specific embodiment
Old working sublevel fill stoping method of the present invention may further comprise the steps:
A, according to the reality of stope, drawing face old working layer position relationship figure in advance marks position, old working support pattern and other parameter in old working and work plane and other tunnel, in detail for next step filling construction is got ready;
B, according to the reality and the prior art situation of stope; Lower, the cold material fillings of sulfur content such as general selection flyash or slag ash; For guaranteeing that the attal size is unlikely to the excessive filling effect that influences, the back pack is screened in casting resin go into the well;
C, according to old working arrangement, top board situation, face propulsion speed, work plane 50m carries out filling (to carrying out stage by stage progressively filling from work plane to the old working that stops adopting line) to old working at least in advance, avoids filling, working face extraction to influence each other;
D, take corresponding sublevel fill stoping method, specifically be divided into following three kinds of situation according to the factors such as layer position, arrangement relation of old working and work plane:
(1) is in this layer and the old working parallel, takes intensive sublevel fill stoping mode, promptly leave not filling section between per two fillings buttress in the old working with work plane; Distance between per two fillings buttress is unsuitable excessive; Generally can not guarantee filling effect, see Fig. 1 greater than span length;
Cause the blind lane that ventilates when preventing that the tunnel drum end from destroying the roadway support state and preventing the filling construction during filling, casting resin is filled to apart from old working top board 0.7m-1.0m and is advisable, and stays airspace;
(2) be in the old working and the top layer old working of this layer and or oblique vertical with work plane; Take general sublevel fill stoping mode; Be to leave not filling section between per two fillings buttress; Distance between per two fillings buttress according to old working top board situation and support pattern, face pressure, with factors such as the position relation decision in other tunnel; Such as the old working support pattern fall behind, face pressure is big, when existing specific positions such as grade separation, usual friendship, oblique to concern with other tunnel; Should dwindle the distance between the filling buttress; Otherwise the distance of widening is seen Fig. 2;
(3) filling method of part bottom old working (tunnel part is in the work plane, part be in the work plane bottom); In old working, demarcate work plane coal cutting base plate line earlier; And then 0.4m (coal breakage is understood not fill area of self-packing when considering the bulging end of old working, coal-winning machine coal cutting) marks fill line under the base plate line; Whole fill under the fill line is seen Fig. 3.
