The purpose of the work is to increase the level of methane gas receiving from natural and technogenic deposits by establishing of the changing regularities of their state and geotechnological properties under the action of pneumodynamic and thermal impact on the mine medium.
On the basis of theoretical studies and experiments, the changing regularities of the parameters of the pneumodynamic and thermal impact on the carbon-contained medium during its physical transformations were established, which allowed to validate the rational parameters of these processes for further improvement of existing and development of new geotechnological methods of integrated methane receiving from natural and technogenic deposits.
The conditions of application and parameters of the pneumodynamic impact method on the gas-saturated coal-rock mass were determined. The technological scheme of the pneumodynamic impact through the surface degassing borehole for methane receiving was developed. It was tested and worked out in experimental researches and industrial testings.
The initial conditions and the main technological parameters of the thermal impact process for carbon-contained raw material for the methane receiving with maximum concentration were established.
The technical documentation for the implementation of effective methods of pneumodynamic and thermal impact on the mine medium at the integrated methane receiving method from natural and technogenic deposits was developed. As a result of the implementation of the proposed comprehensive methane receiving method, 41.68 million m3 of methane was extracted.
The obtained technical and economic indicators show that during the pneumodynamic impact the flow rate from boreholes has increased in 3 times, and the service life of the boreholes was 4.7 times. When conducting thermal impact, the quality of processing of carbon-contained raw materials increased to 30%, and the yield of gas volumes - by 20-25%.
The total economic effect of the implementation of the integrated methane receiving method for geotechnological development of carbon-contained deposits amounted to 6.5 million hrn.
