Estimating Upper Silesian coal mine methane emissions is estimated to arise from the sector of fossil fuel industry (Schwietzke et al.,2016), which also includes activities like coal mining – an industry for which the Upper Silesian Coal Basin (USCB), located in southern Poland and the Czech Re-public, is well known.
Technicians and leads in coal mine design, coal preparation plants and power plants fuelled by rejects as well as construction on an EPC basis. China is by far the largest coal mining nation with a large proportion of its coal mined via advanced underground methods.
Gas explosion has always been an important factor restricting coal mine production safety. The application of machine learning techniques in coal mine gas concentration prediction and early warning can effectively prevent gas explosion accidents. Nearly all traditional prediction models use a regression technique to predict gas concentration.
