Gas Content
The gas content in a seam is a major factor to consider
when looking at outbursts. It affects the probability of an outburst and
also the size of an outburst should one occur. A calculated estimation
of the content of gas must be made in order to assess the mine ventilation
requirements, drainage estimation and the drainage system design.
Methods of estimating the content of gas in a particular region of a coal seam:
Direct Estimation
Indirect Estimation
Probability Estimation
