Research on Knowledge Acquisition for Colliery Gas Forecast Based on Rough Sets and Neural Networks;

By combining rough sets and neural networks,this paper develops a knowledge acquisition model for colliery gas forecast,which consists of four modules:sample refreshment,rough sets preprocessing,neural network training and rules extraction.

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.

The transportation type is the key of utilization of the mine gas,so it's necessary to study the gas transportation technology.

Study on coal gas catalytic decomposition in rotating packed bed reactor;

Based on the test of adding microorganism into coal sample desorbing gas which result in coal gas degradation,regularity of coal gas degradation by microorganism and methanotroph growth in coal sample were studied.

At present, the main technologies for controlling coal gas are physical methods such as ventilation and exhaustion; however, these methods could not fully meet the safety requirements.
