Abstract
The invention relates to a gob-side entry retaining method for a solid filling coal mining building gangue wall. The method comprises the following steps of: building the gangue wall on one side of a filling body in a gob of a filling coal mining surface, and filling coal gangue into a weaving bag or a snakeskin bag and building to form the gangue wall, wherein filling gangue of the filling coal mining surface can be used as the coal gangue directly; and pretightening and timbering the built gangue wall by using a single-layer metal net, a 'W'-shaped steel belt, a ladder beam and a double-ended anchor rod with threads. With the advance of a working surface, the gob-side entry retaining method preserves the complete gangue wall for the mining of the next working surface. The entry retaining method is simple, practical, high in timbering strength and low in cost.
Description
Technical field
The present invention relates to a kind of solid filling coal mining and assemble pack wall gob side entry retaining method, being particularly useful for the filling coal mining work plane does not have the coal column gob side entry retaining.
Background technology
Along with the solid filling coal-mining technique develops gradually, liberated " three times " and pressed coal, improve mine resource recovery ratio, realized the needs of mining area resource and environment harmonic extraction.But the protection pillar about in the filling coal mining between section two stopes stays and establishes width is 20～30m, has caused the loss of a large amount of coal resources, has become the bottleneck that improves the coal resources rate of extraction in the filling coal mining technology.Existing gob-side entry retaining method and relevant patented technology great majority are to adopt the roadside packing technology to carry out on the basis of conventional coal mining activity, the construction technology complexity, need expend more manpower and materials, and this kind mode can to cause inter process to influence each other very serious, inefficiency.
At above problem, a kind of solid filling of the present invention is mined and is assembled pack wall gob side entry retaining method, improved the rate of extraction of coal resources greatly, can increase an escape way for this work plane, can prepare stope drift active workings for next work plane again, can save the tunnelling expense, can alleviate the coal mine excavation imbalance and the nervous situation that continues again, the condition of " Y " type ventilation is provided for high Gassy Coal Face again simultaneously, and on the basis of goaf filling, stay the lane difficulty low, method is simple, and is easy and simple to handle, has important practical significance and wide application prospect.
Summary of the invention
Technical problem: it is simple to the purpose of this invention is to provide a kind of method, and easy construction is safe and reliable, and the solid filling coal mining that has than strong support force assembles pack wall gob side entry retaining method.
Technical scheme: solid filling of the present invention is mined and is assembled pack wall gob side entry retaining method, is to assemble pack wall in filling coal mining face goaf obturation one side, and the width that assembles pack wall is 1.5m～3m, and it is identical with the work plane mining height to assemble the pack wall height; Pack wall is coal mine waste rock is filled and to be assembled and be body of wall with encapsulation bag, and the spoil encapsulation bag of employing is common woven bag or snakeskin bag, and coal mine waste rock directly adopts the filing gangue in mined-out area of even proportioning, and particle diameter is less than 50mm; Adopt single-layer metal net, " W " steel band of model, ladder beam and the supporting of anchor pole pretension then, array pitch is 600mm * 800mm between anchor pole, and " W " steel band of model and ladder beam are right-angled intersection and arrange.
Beneficial effect: the invention solves " three times " and press coal to reach the loss of coal pillar between section two stopes up and down, improved the rate of extraction of coal resources greatly, can increase an escape way for this work plane, can prepare stope drift active workings for next work plane again, can save the tunnelling expense, can alleviate the coal mine excavation imbalance and the pressure that continues again, the condition of " Y " type ventilation is provided for high Gassy Coal Face again simultaneously, and on the basis of goaf filling, stay the lane difficulty low, its method method is simple, practical, the supporting intensity height, cost is low, has practicality widely.
Description of drawings
Fig. 1 is that work plane of the present invention is arranged schematic diagram;
Fig. 2 is the schematic side view that the A-A structure of Fig. 1 assembles the supporting of spoil body of wall;
Fig. 3 is the B-B structure gob side entry retaining schematic diagram of Fig. 1.
Among the figure: 1-goaf filling body, 2-pack wall, 3-encapsulate bag, 4-wire lath, 5-" W " steel band of model, 6-ladder beam, 7-anchor pole.
The specific embodiment
Below in conjunction with accompanying drawing one embodiment of the present of invention are further described:
Figure 1 shows that work plane layout schematic diagram of the present invention, along with work plane is pushed ahead, form the goaf, filling is carried out with spoil in the goaf, form goaf filling body 1, and then goaf filling body 1 one sides assemble pack wall 2, and the width that assembles pack wall 2 is 1.5m～3m, and it is identical with the work plane mining height to assemble pack wall 2 height; Pack wall 2 is coal mine waste rock is filled and to be assembled and be body of wall with encapsulation bag 3, and the spoil encapsulation bag 3 of employing is common woven bag or snakeskin bag, and coal mine waste rock directly adopts the filing gangue in mined-out area of even proportioning, and the spoil particle diameter is less than 50mm; The support pattern of pack wall 2 as shown in Figure 2, adopt single-layer metal net 4, " W " steel band of model 5, ladder beam 6 and anchor pole 7 to carry out the composite reinforcement supporting, array pitch is 600mm * 800mm between anchor pole, wherein " W " steel band of model 5 and ladder beam 6 are " ten " word arranged crosswise, and the final gob side entry retaining lateral view of the present invention that forms as shown in Figure 3.
