Transient processes in coal mining

Authors: Osipova I.А.

Coal mining is a part and parcel of safe and efficient subsoil use. One of the main problems in coal mining in the Russian Federation is coal and gas outbursts. In view of the changed external and internal challenges of coal production Russian mines, it is proposed to consider the problem in the light of intelligent control. The purpose of the study is to demonstrate the internal development of transient processes in a coal mine from the viewpoint of intelligent control. The study objective is probabilistic first-approximation modeling of initiation of coal and gas outbursts. The study is based on the construction of a probabilistic model using the Markov chains. As a result of the study based the probabilistic modeling, we can conclude that it is necessary to update the seismoacoustic monitoring data on condition of surrounding rock mass around headings. The solution is complicated by the need to select a reliability strategy and by the uniqueness of each coal field.

Keywords: transient process, coal seam, coal and gas outbursts, intelligent control, probabilistic model, Markov chain.
