Experiences in Extracting Coal in the Longwall Face Affected by an Endogenous Fire in the OKD, a. s., Czech Republic
Original language description
The issue of endogenous fires in deep mines still remains a concern. These emer-gencies often have an impact on the health and life of people, and/or the bottom line of the mine operation. Black coal mining was behind the dynamic develop-ment in the territory of Ostrava and Karviná, and it is still closely connected with these areas. The development of mining and safety technology has brought pro-gress in this sector and the importance of developing analysers, means of signal-ling endogenous fires as well as means of preventing mine fires, especially the possibility of nitrogen inertization and the construction of more effective explo-sion-proof dams, cannot be overphasized, because a serious risk and frequent cause of endogenous fires of the Karviná part of the OKR (Ostrava-Karviná Coal District) is the self-ignition of the coal mass; the most frequent occurrence of spontaneous fires is at the longwall faces in the caved spaces with the presence of the residual coal fragments. The geological situation of the Longwall Face No. 40 903 at Mining Plant 1, locality Darkov will first be briefly described and evaluat-ed,followed by a description of the laboratory test of the susceptibility of coal to self-ignition and the estimation of the self-ignition phase and the temperature of the endogenous fire outbreak in this longwall face based on the indicator gases. Then, a practical solution of the completion of extracting coal deposits in Longwall Face No. 40 903 is described.
