Abstract
The invention relates to a well hole processing method for an abandoned coal mine. The well hole processing method comprises the following steps: 1) sealing the working surface of the abandoned coal mine by adopting cement; 2) arranging a gas detector in the abandoned coal mine and connecting the detector with an exhaust fan; 3) additionally arranging a gas pumping and exhaust system; 4) filling carbon dioxide or nitrogen dioxide in a sealed well hole; 5) regularly detecting gas in the abandoned coal mine. The well hole processing method provided by the invention has the advantage that by effectively treating the abandoned coal mine, the safety is improved.
Description
Technical field
The invention belongs to technical field of coal mine, be specifically related to the well hole processing method in a kind of discarded colliery.
Background technology
Colliery, after having exploited, forms discarded colliery, and discarded colliery is often due to deal with improperly, the generation of accident on duty, adopts disposable process after having exploited at present, but owing to discarded colliery is containing the assorted generation having garbage, it is easy to cause accident.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, it is an object of the invention to provide the well hole processing method in a kind of discarded colliery, there is the feature in safe handling waste gas colliery.
To achieve these goals, the technical solution used in the present invention is: the well hole processing method in a kind of discarded colliery, it is characterised in that comprise the following steps:
1) work surface in discarded colliery is adopted cement seal；
2) disposing gas indicator in discarded colliery, detector connects air exhausting device；
3) gas exhaust place system is installed additional；
4) in the well hole sealed, it is filled with carbon dioxide or nitrogen dioxide；
5) regularly the gas in discarded colliery is detected.
Described step 4 optimum is adopted as nitrogen dioxide.
The invention has the beneficial effects as follows:
The present invention processes waste gas colliery by effective, the advantage improving degree of safety.
Detailed description of the invention
Below in conjunction with being embodied as the present invention is further discussed below.
The well hole processing method in a kind of discarded colliery, it is characterised in that comprise the following steps:
1) work surface in discarded colliery is adopted cement seal；
2) disposing gas indicator in discarded colliery, detector connects air exhausting device；
3) gas exhaust place system is installed additional；
4) in the well hole sealed, it is filled with carbon dioxide or nitrogen dioxide；
5) regularly the gas in discarded colliery is detected.
Described step 4 optimum is adopted as nitrogen dioxide.
