Analysis of costs of prevention against spontaneous fire hazard based on selected longwalls

[摘要] The paper provides the number of spontaneous fires that have occurred in hard coal mines within the last years as well as exhibits the range of preventive works conducted by mining plants. The authors have provided the characteristics of three longwalls in case of which preventive works against fire hazard were conducted. The range of the preventive works aimed at limiting the fire hazard affecting the exploitation using longwalls has been presented as tables, along with the costs of such works. The costs of the preventive works against fire hazard were listed and analyzed for the selected longwalls based on the specified cost indices.
