Abstract
The invention relates to a water seal drill site gas extraction method of inclined coal seam groups and aims at solving the problem that air leaks into extracted gas in the existing gas extraction technology. According to the method, a mine ventilation roadway, a water filling cross drift passing through each coal seams, inclined water filling coal roadways in each coal seam and a drill site coal roadway are sequentially connected for forming a roadway system, and gas extraction pipes are paved in the system. A plurality of coal holes are drilled in construction coal layers of a site coal roadway. The end connected with the mine ventilation roadway in the water filling cross drift is provided with a sluice gate. The sluice gate is closed, water is fully filled into the water filling cross drift and the inclined water filling coal roadways, water columns are formed, the drill site coal roadway is sealed, and gas in the coal seams sequentially flows into the coal holes, the drill site coal roadway and the gas extraction pipes. The water seal drill site gas extraction method has the advantages that water in the water filling cross drift and the inclined water filling coal roadways fills and is connected with a gas exchange passage of the mine ventilation roadway and the drill site coal roadway, and air in the drill site coal roadway is prevented from leaking into the extracted gas. The water seal drill site gas extraction method is suitable for various inclined coal seams.
Description
Affiliated field the present invention relates to mash gas extraction in mine, belongs to mining technique.
Gas pumping method in the existing mine of background technology, for the coal road that ventilates as the drill site coal road coal hole of in the coal seam, constructing, have the bleed problem of institute's gas pumping of air distinguished and admirable in the drill site coal road.
Summary of the invention is the bleed problem of institute's gas pumping of the existing existing air of mine gas pumping method of solution; Inclined seam crowd water seal drill site gas pumping method of the present invention; By the mine ventilation tunnel, pass the water-filling crossdrift in each coal seam, the inclination water-filling coal road in the coal seam, the drill site coal road in the coal seam and be connected successively, constitute roadway system.The gas pumping pipe is arranged in the roadway system.Many coal holes in drill site coal road construction coal seam.The inherent mine ventilation tunnel end that connects of water-filling crossdrift has sluice gate.Close sluice gate, fills with water in the inclination water-filling coal road in water-filling crossdrift and each coal seam, water column is with the sealing of drill site coal road, and the gas in the coal seam flows coal inlet, drill site coal road, gas pumping pipe successively.
Embodiment of the present invention, water level monitoring pipe, water injection pipe, adjutage pass sluice gate, and personnel monitor, control the water level of water column in the inclination water-filling coal road in the mine ventilation tunnel.
Embodiment of the present invention when the sensible coal-bed gas extraction in many coal holes finishes, is opened sluice gate, and the driving coal road makes it extend to the coal seam boundary of mash gas extraction from drill site coal road end, to many coal holes of construction, coal seam of mash gas extraction not.Afterwards, close sluice gate, fills with water in water-filling crossdrift and inclination water-filling coal road, mash gas extraction is taken in sensible coal seam, new many coal holes.
Advantage of the present invention is the water of the water column in the water-filling crossdrift, inclination water-filling coal road, and filling connects the Gas Exchange passage of mine ventilation tunnel and drill site coal road, the air of blocking the mine ventilation tunnel gas of institute's extraction that bleeds.
Description of drawings
Accompanying drawing inclined seam crowd water seal drill site gas pumping figure
Among the figure, 1 is the coal seam, and 2 are the mine ventilation tunnel, and 3 is the water-filling crossdrift, and 4 is the water-filling crossdrift, and 5 is the drill site coal road, and 6 is the gas pumping pipe, and 7 are inclination water-filling coal road, and 8 is water, and 9 is the coal hole, and 10 is sluice gate.
The specific embodiment is tunneled water-filling crossdrift, inclination water-filling coal road, drill site coal road from the mine ventilation tunnel.Then, many coal holes in drill site coal road construction coal seam, total length is installed the gas pumping pipe along aforementioned tunnel, the construction sluice gate.
