      <abstract xml:lang="ru">
        <p>На отечественных рассолопромыслах залежи каменной соли раз­личной мощности (от 40 до 700 м) и глубины (от 300 до 1400 м) отрабатываются подземным растворением, через скважины. Как пра вило, применяются цилиндрические камеры диаметром 100 м. Камеры располагают по сетке 200x200 м, при этом ширина междукамерных целиков составляет 100 м. Такие размеры целиков недостаточно обос­нованы из-за ограниченного опыта подземного растворения и отсут­ствия апробированных решений. В результате создается опасность разрушения целиков и сдвижений поверхности.</p>

      <abstract xml:lang="en">
        <p>At domestic brine fields deposits of rock salt of various thickness (from 40 to 700 m) and depth (from 300 to 1400 m) are developed by underground dissolution, through wells. As a rule, cylindrical chambers of 100 m diameter are used. The chambers are arranged on a 200x200 m grid, and the width of inter-chamber pillars is 100 m. Such sizes of pillars are insufficiently justified due to limited experience of underground dissolution and lack of tested solutions. As a result, there is a danger of pillars destruction and surface shifts.</p>
