Rating and utilization of coal field gass in Heilongjian Province;

The actuality of drawing coal seam gas and the suggestions to exploit the gas in Jincheng coal bureau;

Borehole sealing mechanism and a new technology for coal seam gas pressure test:a research

Based on the analyzing of the fold and fracture influences to the coal seam gas occurrence,according to the evolution history of regional geology and tectonic characteristics in Huangling No.

Summarization on the vortex engine technique applied in coal mine gas generate electricity

Disaster prediction of coal mine gas based on rough set theory

To the gas in coal mine underground environment,based on the optical absorption character of gas molecule in definite spectrum range,through the analysis of coal mine gas absorption spectrum,optical fiber sensing gas and system is suggested.

Research on the technology of protecting efficiently coal and gas from gushing;

Based on the mechanism of coal and gas outburst,we construct the prediction model of BP neuro-network and make the composite factor of the coal and gas outburst as the feature vector.

Analyzed coal-bed gas hosting features in Zhongling mine through coalfield geological exploration data,summarized practice and application of both walls of roadway drainage technique,affirmed this technique as effective outburst eliminating measure during anthracite roadway advancing.

This paper introduces the formation and the occurrence modes of the gas in coal body, analyzes the influence of the gas on the physical parameters of the coal, and discusses the factors influencing the coal-bed gas drainage.

Constitutive equations of coal containing methane based on mixture theory;

Additional influence due to adsorption should be considered in study mechanics and deformation characters of coal containing methane.
