Обґрунтування заходів щодо збільшення навантаження на очисні вибої при відпрацюванні пл. l1 шахти «Алмазна» Ш/У «Добропільське»

Abstract

The master's qualification work examines the conditions of coal mining at the Almazna mine of DTEK Dobropillyugol, and the bottlenecks are identified. The necessity of development and implementation of measures of methane degassing during cleaning works to increase the load on the bench by gas factor is substantiated. The scheme of ventilation of the excavation sites during the development of the reservoir l1 is substantiated and the main sources of methane emission at the sites, the components of the gas balance and the parameters of its ventilation are determined. An analysis of the measures that can be used to reduce gas emissions at the recess is performed and proposed appropriate for implementation under the conditions under consideration. They have determined the parameters of degassing, which will achieve an efficiency of 0.68 and remove the load on the bench by the gas factor.
