Design of Coal Seam Exploitation in Methane Hazard Conditions: A Case Study

Carrying out exploitation in coal mines with a methane hazard imposes the use of special procedures and analyses numerous parameters order to secure mining teams working underground. The article presents method seam design under conditions for newly prepared seams 404/1 403/1 years 2022 2030 mine southern Poland as case study. It primarily focuses on preparation prognosis. When adequately prepared, this is key correctly designing system opened parts deposit. Based obtained results, appropriate drainage detection systems can be selected. calculations led definition which longwall panel emissions would highest. estimates showed that, from beginning 2028, even between approximately 30 m3/min 45 are forecast, significant increase half 2028 value 57.58 100.00 m3/min. highest emission was forecast A4 A5 panels at 13.53 49.67 m3/min, respectively, A2 B1 41.85 25.46 all advance equal 7 m/d. Therefore, will required designed panels. Considering into longwalls U-type ventilation, calculated effectiveness vary 38.3 40.6%. Higher values require application ventilation drainage, allows obtaining reaching 60.2%, 20 or up 62.6%, level 30–40 Another critical stage utilizing gathered methane; proposition it cogeneration system. heat generated by gas-powered engines should used absorbent coolers that chilling water central air-conditioning mine.
