Abstract
The state of methane control in Polish coal mines is presented in this paper. The ventilation systems of longwall panels are discussed. The necessity of methane drainage usage is emphasised. Those methods should be adapted with respect to the panel ventilation system. The effectiveness of methane drainage relating to using both the methane drainage method and the panel ventilation system, has been described. The principles of methane drainage planning are formulated, as well as practical guidance is given. It should contribute to effective methane drainage in the conditions of Polish coal mines. It is proposed to choose the ventilation and methane drainage systems for longwall panel depending on the predicted methane emission.
