Forecasting coal-gas from re-mining work face of Getting coal mine in Jining coalfield, Shandong Province, China

摘要：

Forecasting the gas from work faces has always been one of the basic studies on safety production of coal mines. In this article we take Geting Mine in Jining mining area as an example, dividing the coal field into five geological units with different characteristics according to the geologic features, and then using mathematic methods to analyze the gas emission volume from work face in different units. Then faults and burial depth are thought to be two of the dominant factors influencing the coal-gas emission volume. And the mathematic model is used to forecast the gas emission volume correctly. It is a good way to forecast the gas volume in the low gas mine.
