Behavior of roof rocks during development of coal seams underlain by eruptive rocks
Authors:
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 working thickness of 1.3-15 meters. The dip angle of the seams is 2-10°. The beds occur at a depth of 30-350 meters. The intervening rocks are mudstones, siltstones and wet sandstones. In the upper part of the coal-bearing strata, sub-basalt conglomerates lie everywhere ...
