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 sectional filling method of old lane.
Background technology
For crossing the special mining face of old working in 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, affected in roof fall, support, cause the problem such as coal resources loss, and traditional whole fill method exists that filling cost is high, length consuming time, the shortcoming that easily normal propelling impacted.
Summary of the invention
The present invention provides a kind of sectional filling method of old lane in order to make up the deficiencies in the 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 is achieved through the following technical solutions:
Sectional filling method of old lane of the present invention, its special character is: comprise the following steps:
A, drawing face old working layer position concerns arrangement diagram, marks in detail position, old working support pattern and other parameter in old working and work plane and other tunnel;
B, select that the sulfur content such as flyash or slag ash are lower, cold material is as casting resin, rear pack is screened in casting resin go into the well;
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.
Sectional filling method of old lane of the present invention, in step D,
(1) be in this layer and the old working parallel with work plane, take intensive sublevel fill stoping mode, be to leave not filling section between every two fillings buttress in old working, distance between every 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 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 every two fillings buttress, distance between every two fillings buttress, when the old working support pattern falls behind, face pressure is large, when existing the 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 work plane, part is in the work plane bottom, during filling, first demarcates work plane coal cutting base plate line in old working, and then 0.4m marks fill line under the base plate line, whole fill under 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 relationship in other tunnel, there is not filling section in old working (stowboard), by adopting flyash, the 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, consuming time short, both having solved stoping period work plane ground presses and manifests, roof fall, support sink and the problem such as coal resources loss, the casting resin waste of having avoided again traditional filling method to cause, the shortcoming of filling length consuming time, reached Fast Filling, do not affect the purpose of working face extraction.
Description of drawings
Accompanying drawing is 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 in Fig. 3, arrow represents advance of the face direction.
In figure, 1 pack portion, 2 old workings, 3 work planes.
The specific embodiment
Sectional filling method of old lane of the present invention comprises the following steps:
A, according to the reality of stope, drawing face old working layer position concerns arrangement diagram in advance, marks in detail position, old working support pattern and other parameter in old working and work plane and other tunnel, for next step filling is constructed ready;
B, according to reality and the prior art situation of stope, the sulfur content such as general selection flyash or slag ash are lower, cold material filling, for guaranteeing that the attal size is unlikely to the excessive filling effect that affects, and screens rear pack to casting resin and goes 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 according to the factors such as layer position, arrangement relation of old working and work plane, specifically be divided into following three kinds of situations:
(1) be in this layer and the old working parallel with work plane, take intensive sublevel fill stoping mode, namely leave not filling section between every two fillings buttress in old working, distance between every two fillings buttress is unsuitable excessive, generally can not guarantee filling effect greater than span length, see Fig. 1;
During filling, for preventing that the tunnel drum end from causing the blind lane that ventilates when destroying the roadway support state and preventing the filling construction, casting resin is filled to apart from old working top board 0.7m-1.0m and is advisable, and stays airspace;
(2) be in 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 every two fillings buttress, distance between every two fillings buttress is according to old working top board situation and support pattern, face pressure, determine with the factors such as position relationship in other tunnel, such as the old working support pattern falls behind, face pressure is large, when existing the 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 work plane, part is in the work plane bottom), first demarcate work plane coal cutting base plate line in old working, and then when under the base plate line, 0.4m(considers the old working drum end, coal-winning machine coal cutting coal breakage can self-packing fill area not) mark fill line, whole fill under fill line is seen Fig. 3.
