Production studies using a specially developed methodology have shown that the pillar system of potash development at the Starobinsky deposit results in the release of combustible gases into the existing mine workings. The main component of these gases is methane, heavy hydrocarbons are emitted in insignificant amounts. Under normal conditions the absolute gas emission at the mine sites is insignificant. In the total gas balance of the sites, the main part (up to 98%) is gas emission from the mined-out space.
In the last decade, the USSR has implemented an extensive program of reconstruction of existing potash mines and construction of new potash mines, which has brought our country to the first place in the world in terms of potash fertilizer production. ...
