Abstract: In this article the program and technique of carrying out of researches on coal bed degassing with performance of underground hydraulic fracturing in the conditions of mine "Chertinskaya-Koksovaya" is resulted. The main purpose of hydraulic fracturing technology tests is: determination of effective parameters of hydraulic fracturing, fracturing zone, gas content of initial and residual, volume and dynamics of methane capturing outside the zone of influence of treatment works and in the zone, gas content of treatment production outside and in the zone of hydraulic fracturing, degassing efficiency in general. In the process of operational testing the following tasks were solved: 1) evaluation of the impact of hydraulic fracturing technology on reservoir degassing; 2) geophysical studies of the state of the carbon mass in the pilot area before and after the hydraulic fracturing; 3) measurements of methane flow from wells in the cleanout bottomhole outside and in the zone of influence of treatment works, processing the results of observations; 4) observations of the manifestation of rock pressure in the cleanout bottomhole when crossing the zone of hydraulic fracturing.

Key words: underground mining degassing hydraulic fracturing methane gas emission rate
