Behavior of roof rocks during mining of coal seams erstand overlain by eruptive rocks

Abstract
The Maykhinskoye lignite deposit (in the southern part of Primorsky Krai) is a suite of 20 gently sloping seams, 7 of which have a mineable thickness of 1.3-15 meters. The dip angle of the seams is 2-10°. The seams occur at a depth of 30-350 meters. The host rocks are mudstones, siltstones and water-bearing sandstones. In the upper part of the coal-bearing strata, sub-basalt conglomerates are widespread ...
