DEVELOPERS: academic of NAS of Ukraine Pivniak G.F., prof. Bondarenko V.I., prof. Tabachenko М.М., associate prof. Falshtinskii V.S., associate prof. Dichkovskii R.А., associate prof. Svietkina S.Yu., engineer Timoshenko Ye.V., engineer Lozinskii V.G, engineer Saik P.B.
 
PROJECT ESSENCE: New technology schemes of WUCG have been developed and they allow to provide mining, complex processing of gasification products and recuperation of the rock mass heat. New construction of gas generator in regime of controlled gasification accounting for natural factors and technological parameters in closed environmental safety cycle has been developed. 
 
PRINCIPAL SCHEME OF WELL UNDERGROUND GASIFICATION OF THE COAL SEAMS
PRINCIPAL SCHEME OF WELL UNDERGROUND GASIFICATION OF THE COAL SEAMS
1 – coal seam;  2 – injection well; 3 – gas-extractive well; 4 - mobile incendiary devices; 5 – injection pipeline; 6 – gas-extractive pipeline; 7 – heat-exchanger recovery; 8 – fire chuckhole; 9 – elaborated area; 10 – tips of vertical and horizontal wells; 11 – surface
 
PARAMETERS OF SPREADING OF THE TEMPERATURE FIELD OF THE ROCK-COAL ARRAY ALONG THE ROCK SEAM
PARAMETERS OF SPREADING OF THE TEMPERATURE FIELD OF THE ROCK-COAL ARRAY ALONG THE ROCK SEAM
 
APPLICATION AREA: Off-grade stocks of black and brown coal with the seams depth from 50 m and more, dropping angle 0 – 90 degrees, rock bed thickness 0,4 m and more at under-mining and up-mining in ascending and descending order, and also fuel slates, heavy (paraffinized) oil.
 
ECONOMIC EFFECT:
  • Productivity of the station of WUCG: 13,6 – 76 thousands m3 of generator gas with combustion heat 5,4 – 11,7 MDj/m3; 134,8 – 431,7 t. of chemical substances.
  • Prime cost: the station – 102-293,4 UAH/thousands m3; power energy 0,09-0,24 UAH/kW*hour.
  • Pay-back period for enterprise 1,5-3,0 years.

    A lot of innovations have been occurring in the mining industry with the development of new technologies. This is surely one of those notable advancements to use in the underground coal gasification process. They allow providing mining, complex processing of gasification products and recuperation of the rock mass heat. internet providers

    What exactly are the advantages that the mining field would be having when adapting to this technology? And how efficient would it be to use this on a large mine fields? I couldn’t find answers to this question and if anyone could help me with it, I would be thankful.

    Gasification is imperfect burning solid fuels like fire wood or gas without sufficient air to complete incineration. And you giving here informative information on it which is increasing knowledge of science students who are coming to take personal statement professional writing help from me as I am a personal statement writer at Personal statement Folks. Thanks for fantastic post!

    Wasn't involved in it but several years ago there was such a plant near me. After 3 years they went bankrupt and closed down. From employees I was told it was not cost effective. The process worked as they had tankers hauling fuel. Dissertation Helps UK

    I think this is really helpful for lots of people.Actually i don't have any idea about the WUCG .Now i got some new information.I am working as a staff of voucher codes based company in UK.I am taking this underground information as my project.Can you give me the detailed information?

    The worst part of it was that the software only worked intermittently and the data was not accurate. You obviously canot confront anyone about what you have discovered if the information is not right. cake shop in Bhopal

    A lot of innovation has been happening in the mining manufacturing with the growth of new technologies. This is definitely one of those distinguished advancements to use in the subversive coal gasification process.
