Abstract
The invention relates to a gas treatment method, in particular to a method for performing extraction treatment on the corner gas on the work faces of adjacent roadways. The problems that according to existing treatment on corner gas on the work faces, the tunneling workload is large, cost is high, and an extraction pipeline is prone to damage are solved. After an air returning gate roadway of a coal face A is finished, a return airway of a next work face B is arranged in advance at 30-meter interval, the gas extraction pipeline is arranged in the return airway, a gas extraction drill site is arranged in the return airway every 80 meters, drilling is constructed in the gas extraction drill sites to extract the corner gas on the coal face A, and after the coal face A is extracted, holes towards the coal face B are drilled in the drill sites for gas extraction. The method has the beneficial effects that the purpose that the extraction pipeline is arranged on one roadway and the two adjacent work faces are commonly used is achieved, the project of repeated construction of the gas extraction drill sites in the two roadways is avoided, and the construction progress is greatly increased.
Description
Technical field
The present invention relates to a kind of mash gas harnessing method, be specially a kind of adjacent tunnel extraction control face gas at upper corner method.
Background technology
At present, coal mine fully-mechanized mining working takes extraction gas at upper corner control face gas before back production old power station, the ancillary facility such as gas pumping station and sump is generally arranged in the lane, panel of this work plane, construction extraction pipeline during extraction of drilling is arranged in this work plane air return way lane, and period does not affect face haulage circuit in order to drill, need to arrange a gas drainage under suction drill site at interval of about 80 meters in air return way, excavation work amount is larger.Gas drainage pipeline is arranged in air return way, easily causes gas to reveal the installations and facilities infringements such as extraction pipeline during air return way transport if any unexpected, and extraction pipeline gas leakage very easily to cause in air return way gas alarming or transfinites, ineffective to trouble free service.The schemes synthesis of current use shows as: excavation work amount is many, cost is large.
Summary of the invention
The present invention is large in order to solve the headwork amount that exists in existing face upper corner angle gas control, and cost is high, and extraction pipeline is the problem such as damaged easily, provides a kind of adjacent tunnel extraction control face gas at upper corner method.
Technical scheme of the present invention is as follows: a kind of adjacent tunnel extraction control face gas at upper corner method, after the air return way of coal-face A completes, the return airway of next work plane B is arranged at 30 meters, interval in advance, in the return airway that gas drainage pipeline is arranged in, a gas drainage under suction drill site is arranged at interval of about 80 meters in return airway, construction drill extraction coal-face A gas at upper corner in gas drainage under suction drill site, after extraction coal-face A terminates, and then boring to draw out methane what beat towards coal-face B in drill site.
Compared with prior art, scheme of the present invention is by arranging that in adjacent tunnel drill site and gas drainage pipeline carry out the gas of extraction face upper corner angle, accomplish that extraction pipeline is arranged in a lane, the object that two adjacent work planes use jointly, avoid in two lanes the engineering repeating construction gas drainage under suction drill site, substantially increase construction speed.Do not construct the air return way tunnel of gas treatment technique as haulage drift, avoids extraction installations and facilities such as breaking extraction pipeline and cause gas to reveal and gas alarming or the gas accident such as to transfinite in extraction pipeline gas leakage generation air return way.
Accompanying drawing explanation
Fig. 1 is the solution of the present invention arrangement diagram;
In figure: 1-air return way, 2-return airway, 3-gas drainage pipeline, 4-gas pumping station, 5-gas drainage under suction drill site, 6-holes, 7-fire dam, 8-fire dam, 9-air crossing, 10-bidirectional ventilation door, 11-regulation wind window.
Detailed description of the invention
As schematically shown in Figure 1, a kind of adjacent tunnel extraction control face gas at upper corner method, after the air return way 1 of coal-face A completes, the return airway 2 of next work plane B is arranged at 30 meters, interval in advance, in the return airway 2 that gas drainage pipeline 3 is arranged in, a gas drainage under suction drill site 5 is arranged at interval of about 80 meters in return airway 2, construction drill 6 extraction coal-face A gas at upper corner in gas drainage under suction drill site 5, after extraction coal-face A terminates, and then boring to draw out methane what beat towards coal-face B in drill site.
Fire dam 8 is provided with between described air return way 1 and return airway 2, air crossing 9 is set up between the tunnel of coal-face A and air return way 1, bidirectional ventilation door 10 is provided with in air return way 1 rear end, front end is provided with fire dam 7, is also provided with the gas pumping station 4 connecting gas drainage pipeline in air return way 1 rear end.By above layout, the gas of two work planes can be made to be able to efficient extraction, and save the drill site construction quantity in a tunnel, reduce the amount of labour and human cost.Do not construct air return way 1 tunnel of gas treatment technique as the haulage drift in coal mining exploitation process, avoids haulage device and coal and break the extraction installations and facilities such as extraction pipeline and cause gas to reveal and gas alarming or the gas accident such as to transfinite in extraction pipeline gas leakage generation air return way.
