Abstract

1. Способ подготовки и отработки сближенных пологих пластов, включающий проходку выемочных штреков по двум пластам, сбиваемых уклонами, проветривание тупиковых забоев вентиляционными установками местного проветривания и подачу отбитой руды от проходки выемочных штреков по верхнему пласту через рудоспускные скважины на конвейерную линию, смонтированную на нижнем пласте, отличающийся тем, что выемочные и конвейерный штреки по нижнему пласту проходят прямым порядком до границы выемочного участка и их проветривание производят за счет общешахтной депрессии по возвратноточной схеме с использованием наиболее удаленной междуштрековой сбойки, затем осуществляют проходку спиралеобразного уклона на верхний пласт, после чего в обратном порядке проходят выемочный штрек по верхнему пласту с его проветриванием через скважины, с установленными на них вентиляторами, а после сбойки выемочного штрека с вентиляционными выработками верхнего пласта, проветривание осуществляют по возвратноточной схеме с движением воздуха в прямом порядке по выработкам на нижнем пласте и с обратным движением воздуха по выработкам верхнего пласта.2. Способ по п.1, отличающийся тем, что образование вентиляционных штреков на обоих пластах производят при выемке запасов руды в камере в процессе прямого порядка отработки выемочного участка.3. Способ по п.1, отличающийся тем, что проветривание выработок на нижнем пласте производят с использованием вентиляционных восстающих выработок, соединяющих вентиляционные штреки.1. The method of preparation and mining of adjoining shallow formations, including the excavation of drift drifts along two formations, knocked down by slopes, ventilation of deadlocks with local ventilation units and the supply of broken ore from the excavation of drift drifts through the upper layer through the drainage wells mounted on the conveyor line mounted on the lower conveyor line , characterized in that the excavation and conveyor drifts along the lower layer are in direct order to the boundary of the excavation section and their ventilation is carried out by mine depression according to the return flow pattern using the most distant inter-track fault, then a spiral-like slope is drilled to the upper formation, after which the excavation drift through the upper formation with its ventilation through the wells, with fans installed on them, and after breaking the excavation drift with ventilation workings of the upper layer, ventilation is carried out according to the return flow pattern with the movement of air in direct order along the workings on the lower layer and with the return air movement over the workings of the upper layer. 2. The method according to claim 1, characterized in that the formation of ventilation drifts on both layers is carried out during the extraction of ore reserves in the chamber in the process of direct mining of the extraction section. The method according to claim 1, characterized in that the ventilation of the workings on the lower layer is carried out using ventilation uprising workings connecting the ventilation drifts.
