Abstract
The utility model discloses an independent coal gas drainage well with spoke-shaped holes layout, belonging to the mining technology. In order to resolve the existing problem that the coal mine gas pumped within the mine mutually interferes with the coal production, the utility model is to construct shafts, coal roadways, coal holes in a new mine for independent gas drainage. Coal holes are in spoke-shaped layout around the center shaft, so that the drainage area is expanded. Low water seals coal roadways and tunnels which are filled with water for the isolation with the shaft to ensure the pure gas drainage. The utility model is applicable to various mining fields, can lead to a large-scale gas drainage from coal mines for gas supply ahead of mass production and subsequently eliminate the root cause of gas-related accidents.
Description
Technical field the utility model relates to the Device in Gas in the extraction coal seam, belongs to mining technique.
In the background technology coal seam contained flammable can quick-fried Device in Gas, need before producing coal to extract out to concentrate to drain into ground from the coal seam, be called " gas drainage under suction ".At present, gas drainage under suction utilizes the producing coal roadway to carry out in the producing coal mine, interferes with each other with producing coal.The purpose of this utility model provides the independent gas drainage under suction well that a kind of spoke-like coal hole is arranged, gas drainage under suction and producing coal are independently carried out in 2 wells, thus both problems of interfering with each other of solution prior art.
The independent gas drainage under suction well that summary of the invention the utility model spoke-like coal hole is arranged connects ground and coal seam by pit shaft.In the well, coal road and the Device in Gas that the collection coal seam, many coal holes in the coal seam construction pours in from coal road.Coal road connects pit shaft with the low level water seal tunnel that absolute altitude is lower than coal road.When drawing out methane gas, fills with water in the low level water seal tunnel is opened the ground aspiration pump, and collected Device in Gas in the coal road enters gas well, ground tracheae, is evacuated to ground by the ground aspiration pump.
Implement a kind of coal hole arrangement of the independent gas drainage under suction well of the utility model spoke-like coal hole layout: many coal holes are the center with the pit shaft, in the coal seam, be spoke-like and arrange, and the spacing between the promptly adjacent coal hole, the growth long with the hole increases.
Implement the ventilation wind path of the independent gas drainage under suction well arranged in the utility model spoke-like coal hole: personnel are in coal road during operation, discharge the water in the low level water seal tunnel, constitute the ventilation wind path by ground aspiration pump, ground tracheae, gas well, coal road, low level water seal tunnel, pit shaft.
Advantage of the present utility model is to eliminate the mutual interference mutually of prior art gas drainage under suction and producing coal, with the Device in Gas in the short coal road large tracts of land extraction pit shaft periphery coal seam.
Description of drawings is described further the utility model below in conjunction with accompanying drawing.
The independent gas drainage under suction well that accompanying drawing spoke-like coal hole is arranged
Among the figure, coal road 4-1, coal road 4-2 are connected with pit shaft 3 with low level water seal tunnel 7-1, the low level water seal tunnel 7-2 that absolute altitude is lower than them respectively.Tunnel among the figure between sluice gate 6 and the coal road 4-2 is low level water seal tunnel 7-2.Show among the figure that many coal holes 5 in the coal seam 2 are that the center is the spoke-like layout with pit shaft 3.
The specific embodiment as seen from the figure, coal road 4-1 is connected successively with 4-2, gas well 8, ground tracheae 9 and ground aspiration pump 10.When being full of water in low level water seal tunnel 7-1, the low level water seal tunnel 7-2, the exchange of the gas of coal road 4-1, coal road 4-2 and pit shaft 3 is cut off.At this moment, open ground aspiration pump 10, be collected in the Device in Gas in coal road 4-1, the coal road 4-2, enter gas well 8, ground tracheae 9 is pumped down to ground 1.Discharge the water in low level water seal tunnel 7-1, the low level water seal tunnel 7-2, coal road 4-1, coal road 4-2 are connected with pit shaft 3, and constitute ventilation wind path by ground aspiration pump 10, ground tracheae 9, gas well 8, coal road 4-1 and coal road 4-2, low level water seal tunnel 7-1 and low level water seal tunnel 7-2, pit shaft 3 this moment.
