      <abstract xml:lang="ru">
        <p>На шахтах Прибалтийского сланцевого бассейна в течение нескольких лет проводились широкие промышленные испытания различных вари­антов камерной системы разработки. С целью правильного определения параметров системы на шахте № 3 комбината «Сланцы» изучалось прояв­ление горного давления, в частности, исследовалась устойчивость целиков. Промышленный пласт горючих сланцев общей мощностью 2 —3 м за­легает в условиях бассейна почти горизонтально на глубине 30—100 м и состоит из четырех слоев горючего сланца и трех породных прослойков. В кровле и почве пласта известняки переслаиваются с глинистыми и горю­чими сланцами.</p>

        <p>In the mines of the Baltic oil shale basin, extensive industrial tests of different variants of the chamber mining system have been carried out for several years. In order to correctly determine the parameters of the system, the manifestation of mining pressure was studied at the mine No. 3 of the Slantsy Combine, in particular, the stability of the pillars was investigated. The industrial oil shale bed with a total thickness of 2 -3 m is almost horizontal at a depth of 30-100 m in the conditions of the basin and consists of four layers of oil shale and three rock layers. In the roof and soil of the formation, limestones are interbedded with clay and oil shale.</p>
