      <abstract xml:lang="ru">
        <p>При подземных горных работах выделяется большое количество газа, поэтому производительность горных работ снижается, а риски возрастают. Эффективное удаление метана из угольного пласта и окружающих пород в подземные выработки не только повышает безопасность, но и улучшает производительность. Дегазация угольного метана должна выполняться, когда вентиляционный воздух не может разбавить выбросы метана в шахте до уровня ниже допустимых пределов. Одним из методов дегазации метана является использование скважин вкрест простирания трещиноватости, заключающийся в бурении скважин от проходческого забоя до ненапряженной зоны в толще кровли или подошвы отработанного пласта. Это – основной метод, используемый на угольной шахте Табас № 1. Одним из эффективных параметров является расстояние между скважинами дегазации метана, которое напрямую влияет на длину скважин. Исследование основано на измерении содержания метана вентиляционных струй датчиками метана и анемометрами, размещенными на панели очистного забоя, а также на измерении количества дегазированного метана. Полученные и проанализированные данные были использованы для определения подходящего расстояния между скважинами дегазации угольного метана с использованием скважин вкрест простирания системы трещин. В полевых исследованиях были испытаны три схемы расположения скважин с разным расстоянием между кустами скважин на панели E4 угольной шахты Табас № 1. Сравнивалось количество газа, отводимого по этим схемам. Наибольшая эффективность дегазации метана достигается при расстоянии 9-12 м между скважинами дегазации угольного метана.</p>

      <abstract xml:lang="en">
        <p>A large amount of gas is emitted during underground mining processes, so mining productivity decreases and safety risks increase. Efficient methane drainage from the coal seam and surrounding rocks in underground mines not only improves safety but also leads to higher productivity. Methane drainage must be performed when the ventilation air cannot dilute the methane emissions in the mine to a level below the allowed limits. The cross-measure borehole method is one of the methane drainage methods that involves drilling boreholes from the tailgate roadway to an un-stressed zone in the roof or floor stratum of a mined seam. This is the main method used in Tabas coal mine N 1. One of the effective parameters in this method is the distance between methane drainage stations, which has a direct effect on the length of boreholes required for drainage. This study was based on the measurement of ventilation air methane by methane sensors and anemometers placed at the longwall panel as well as measuring the amount of methane drainage. Moreover, in this study, the obtained and analyzed data were used to determine the suitable distance between methane drainage stations based on the cross-measure borehole method. In a field test, three borehole arrangements with different station distances in Panel E4 of Tabas coal mine N 1 were investigated. Then, the amounts of gas drained from these arrangements were compared with each other. The highest methane drainage efficiency was achieved for distances in the range of 9-12 m between methane drainage stations.</p>
