Integrated research of gas environment in mines

The article presents an approach to the integrated research of the gas environment in underground mines. The lab-scale testing and field research procedures are described. The field research includes mine gas survey, local measurement of gas emission of self-propelling diesel machines, gas emission measurement in blasting and at storages of broken rocks, combustion gas emission measurement in underground boreholes, as well as in situ sampling. The lab-scale tests determine gas composition of mine air samples, analyze content of occluded gases in rocks, and analyze chromatography of free and occluded gases in rock samples. It is recommended to use both the field and lab test data in parametrization of ventilation network models and in the mathematical modeling of gas–air mixture flow in underground roadways. The proposed integrated approach to the gas environment investigation in operating mines can help improve the quality and practical value of the reports on composition, scale, location and nature of gas emissions in underground mines.

Keywords: mine, gas environment, gas content of rocks, field research, lab-scale testing, ventilation network, gas concentration, gas emission.
