Monitoring the effectiveness of the coal mine degassing system-the basis for safe work of miners

Authors: Malashkina V.A.

The process of degassing coal mines has become an integral part of the technological process of coal mining in the development of gas-bearing coal deposits. Research data and practice confirm the impact of degassing efficiency on all stages of the technological process, and has a significant positive impact on the technology and economy of the faces, sections and mines as a whole. Continuous monitoring of the main performance indicators of the degassing system (degassing and gas-pumping plants) allows early detection of dangerous and adverse factors that affect the safety of miners. The main indicators of the efficiency of degassing systems should include not only compliance with regulatory documents, the content of methane in each mining operation,but also the continuity of the degassing and gas-pumping plants. This indicator can be provided by the stability of the underground vacuum degassing gas pipeline and vacuum pumping station. Timely condensate discharge and maximum tightness of the vacuum gas pipeline for these conditions must be provided. Data on monitoring these indicators affect the quality of operation of the vacuum pumping station and, consequently, to ensure a safe situation in the mine workings. Comparison of current indicators with standard ones in the current time mode will allow timely detection of dangerous situations and make appropriate decisions aimed at reducing accidents at gas-rich coal mines

Keywords: degassing, hydraulic co-resisting, underground vacuum gas pipeline, methane-air mixture, fiberglass pipeline, tightness, greenhouse effect, monitoring, safety.
