ТЕХНОЛОГИЯ ДОБЫЧИ ГАЗООБРАЗНОГО ТОПЛИВА НА ОСНОВЕ КОМПЛЕКСНОЙ ПОДЗЕМНОЙ ГАЗИФИКАЦИИ И ДЕГАЗАЦИИ УГОЛЬНЫХ ПЛАСТОВ

THE TECHNOLOGY OF EXTRACTING GASEOUS FUEL BASED ON COMPREHENSIVE IN SITU GASIFICATION AND COALBED DEGASSING

ТЕХНОЛОГИЯ ДОБЫЧИ ГАЗООБРАЗНОГО ТОПЛИВА НА ОСНОВЕ КОМПЛЕКСНОЙ ПОДЗЕМНОЙ ГАЗИФИКАЦИИ И ДЕГАЗАЦИИ УГОЛЬНЫХ ПЛАСТОВ

Abstract

The study considers a comprehensive technology (designed and patented by the authors) of developing coal and methane deposits which combines in situ gasification of lower coalbeds in the suite of rock bump hazardous gassy beds, extraction of coal methane and mechanized mining of coal. The first stage of the technology consists in mining gaseous fuel that enables one to extract up to 15-20 of total energy from the suite of coalbeds. Geodynamic zoning is used to select positions for boring wells.Using the suggested technology makes it possible to solve a number of tasks simultaneously. First of all that is extracting gaseous fuel from the suite of coalbeds without running any mining works while retaining principal coalbeds in the suite and preparing them for future processing (unloading and degassing).During the first phase the methane-coal deposit works as a gas deposit only, the gas having two sources extracted methane (which includes its locked forms, absorbed and adsorbed) and the products of partial incineration of thin coalbeds, riders and seams from thee suite. The second stage consists in deep degassing and unloading of coal beds which sharply reduces the hazards of methane explosion and rock bumps, thus increasing the productivity of mechanized coal mining. During the second stage coal is mined in long poles with the account of degassing and unloading of coal beds, plus the data on gas dynamic structure of coal rock massif

В статье рассматривается комплексная технология (разработанная и запатентованная авторами) отработки углеметановых месторождений, совмещающая подземную газификацию нижних пластов угля в свите удароопасных газообильных пластов, извлечение угольного метана и механизированную добычу угля. Первым этапом технологии является добыча газообразного топлива, позволяющая извлечь до 15-20 суммарной энергии свиты угольных пластов. Для выбора мест бурения скважин используется геодинамическое районирование.Применение предлагаемой технологии позволяет одновременно решить ряд задач, прежде всего это получение газообразного топлива из свиты угольных пластов без ведения горных работ при сохранении основных пластов в свите и их подготовке к отработке (разгрузка, дегазация).На первом этапе углеметановое месторождение выступает как газовое, причем газ имеет два источника извлеченный метан (включая связанный абсорбированный и адсорбированный) и продукты неполного сгорания маломощных пластов и пропластстков в свите. Второй этап это глубокая дегазация и разгрузка угольных пластов, резко снижающие риски взрывов метанов, выбросов и горных ударов и повышающие производительность механированной добычи угля. На втором этапе производится добыча угля длинными столбами с учетом проведенных ранее дегазации и разгрузки, а также сведений о геодинамическом строении углепородного массива.
