RECOVERY AND INDUSTRIAL UTILISATION OF COALBED METHANE IN JASTRZFBSKA COAL COMPANY MINING AREA

摘要

The paper presents resources and present status ofcoal seam methane from the mining field of JSW SA., as well astrends in its application both in JSW SA, plants and in othercommercial law subjects, created on the basis of its assets. Onthe instance of actions and measures taken and programs carriedout in the period 19974999, dynamics of growth of methaneutilization was shown. Perspectives of methane drainage werepresented, with regard to both work and realization ofrestructuring programs in the mining industry. Demand andsupply of methane were discussed, taking into account real andpotential opportunities. An assessment was made of realizationstatus in respect to power industry programs, their impact inreduction of emissions to atmosphere both of methane and ofother pollutants. An evaluation of influence exerted by thesemeasures on the performance of cogeneration of heat andelectricity was prepared Projects in progress were presented,pertaining to increase of gas-firing in the existing boilerinstallations, investment projects referring to installation of gasengines for cogeneration of heat and electricity, utilization ofdistribution network for a maximum utilization of gas anddesigns of power generation systems using methane for airconditioning in the mines. An evaluation was made of theprogram in progress in its ecological and economical aspects, aswell as real and potential opportunities for additional measures.
