Description
Technical field
The present invention relates to coalmine ventilation technical field, specially a kind of for gas pumping under coal mine negative pressure pressure stabilizing dress
It sets.
Background technique
Coal mine is the mankind in the region of the mining area exploitation coal resources rich in coal, is generally divided into underground mine and outdoor coal
Mine is typically chosen to underground when coal seam is remote from earth's surface and digs tunnel digging coal, this is underground mine, when coal seam is away from earth's surface
Distance it is close when, be typically chosen directly removing surface soil layer excavate coal, this is open coal mine, China's overwhelming majority coal mine category
In underground mine, coal mine is the proportional space that the mankind are excavated when digging is rich in the geological stratification for having coal, generally includes lane
Road, well cave and face etc..In order to guarantee the needs of coal mine downhole safety production, carrying out pump drainage to the gas in coal seam is one
Important process one of of the item as coal mine downhole safety guarantee.It is that gas exhaust pumps as the main tool to gas exhaust, one
As in the case of gas exhaust pump the bearing and the frequent quilt of sealing ring that gas exhaust during pump drainage pumps are carried out to coal-bed gas
Entrained cinder and rock ballast abrasion in the gas air-flow quickly flowed, and cause gas exhaust pump that cannot use, it seriously affects
The safety in production of underground coal mine；The gas exhaust pump of underground coal mine, which has, at present uses installation gas-slag separation device will be in gas air-flow
Mixed cinder and rock ballast are separated, and are solved cinder and rock ballast and are given gas exhaust pump bring wear problem, however gas
The gas of pump drainage pump institute's pump drainage not only has the methane gas in drilling, but the prior art still remains not during coal mining
Foot, especially in the mode of ventilation, such as:
As continuous coal mining will appear the excessively high situation of gas density during coal mining, this just need to coal mine into
Row ventilation, existing draft type are all to be aerated using air-introduced machine exhausting, but will appear coal mine internal pressure mistake in this way
Low situation, influence to mine is normally carried out, so be unable to satisfy needed for the prior art.
Summary of the invention
The purpose of the present invention is to provide a kind of negative pressure stabilizing device for gas pumping under a coal mine, to solve above-mentioned back
The problem of being proposed in scape technology.
