Abstract
Изобретение относится к горному делу и может быть использовано при разработке месторождений каменного угля для обеспечения безопасности ведения горных работ шахтным и др. способами и попутной добычи углеводородных газов. Задача предполагаемого изобретения - повышение эффективности разработки месторождений каменного угля с получением углеводородных газов и снижение риска внезапных выбросов и взрывов воздушно-метановой смеси в шахтах при проведении горных работ. В способе подземной разработки залежи каменного угля, включающем вскрытие угольного пласта скважинами и подачу под давлением внутрь пласта воздушно-газовых смесей и/или жидкостей, не опасных для жизни и здоровья людей, с помощью различных метдоов, например геофизических, определяют в угольной залежи участки с наибольшим содержанием углеводородных газов, в зависимости от газоносности и проницаемости этих участков, расчетным путем разбивают залежь на блоки, с поверхности земли каждого блока бурят до расчетной глубины на расчетном расстоянии друг от друга закачную и откачную скважины, оборудуют их фонтанной арматурой и насосно-компрессорными трубами, а закачную - дополнительно волновым излучателем, из закачной скважины по угольному пласту проходят несколько наклонно ориентированных стволов, обсаживают их перфорированными трубами и оборудуют волновыми отражателями и пакерами, по насосно-компрессорным трубам подают в угольный пласт под давлением воздушно-газовую смесь и/или жидкость с одновременным наложением упругих волн, для которых она/они служат волноводом, упругие волны ориентируют волновым отражателем и пакером в сторону откачной скважины, таким образом, наводят на межскважинном участке блока расчетную проницаемость газовмещающего полезного ископаемого, забор выжимаемого углеводородного газа, осуществляют из откачной скважины, обработанные блоки угольной залежи разрабатывают подземным способом.The invention relates to mining and can be used in the development of deposits of coal to ensure the safety of mining operations by mining and other methods and associated production of hydrocarbon gases. The task of the proposed invention is to increase the efficiency of mining of coal deposits with the production of hydrocarbon gases and reduce the risk of sudden emissions and explosions of the air-methane mixture in mines during mining operations. In the underground mining method, coal deposits, which include the opening of a coal seam by wells and the supply of air-gas mixtures and / or liquids not hazardous to human life and health under pressure, using various methodologies, such as geophysical, determine with Depending on the gas content and permeability of these areas, the maximum content of hydrocarbon gases is divided into blocks by calculation, from the surface of each block they are drilled to the calculated depth at the calculated distance The injection and pumping wells are separated from each other, equipped with gushing fittings and tubing pipes, and the injection wells are additionally equipped with a wave emitter. tubing pipes are fed into the coal seam under pressure by an air-gas mixture and / or a fluid with the simultaneous imposition of elastic waves for which she / they serve as a wave guide, are elastic e waves are oriented with a wave reflector and a packer in the direction of the pumping well; thus, the calculated permeability of the gas-bearing mineral, the squeezed hydrocarbon gas is extracted from the wellbore section of the block;
