Abstract
Изобретение относитс к угольной промьшшенности и может быть использовано на шахтах, разрабатываю- свиты угольных пластов, опасных по внезапным выбросам угл и газа. Целью изобретени вл етс повьппе- ние эффективности разработки за счет сокращений потерь добычи угл и снижени трудоемкости работ по поддержанию действук цей линии очистных забоев . Способ основан на разработке выбросоопасных угольных пластов в зоне взаимного вли ни опорного дав- лени при встречном подвигании очистных забоев. Очистна выемка на смеж- ных гшастах в зоне вли ни опорного давлени осуществл етс периодически , поочередно на каждом пласте. Врем остановки очистных забоев определ етс периодом, необходимлш дл эффективной естественной дегазации вынимаемой полосы угл , и определ етс соотношением , где t - ин- .тервал времени, необходимый дп формировани зоны естественной дегазации , сут; г - ширина оны естественной дегазации, м; v - безопасна скорость подвигани очистного забо , м/сут. Отработка дегазированной полосы угл производитс вначале на .одном пласте, в то врем как на другом пласте формируетс зона дегазации . Размеры зон опорного давлени и пшрину зон естественной дегазаций определ ют известными способами. 1 ил. (ЛThe invention relates to coal industry and can be used in mines, developing the formations of coal seams, which are dangerous due to sudden emissions of coal and gas. The aim of the invention is to increase the efficiency of development by reducing the loss of coal mining and reducing the labor intensity of the work on maintaining the working face of the longwall. The method is based on the development of outburst coal seams in the zone of mutual influence of the reference pressure during the counter-movement of the working faces. The clearing recess on adjacent gshastakh in the zone of influence of the reference pressure is carried out periodically, alternately on each layer. The stoppage time for stopping faces is determined by the period required for effective natural degassing of the coal strip to be extracted, and is determined by the ratio, where t is the time interval required for the formation of the natural degassing zone, days; g is the width of the natural degassing, m; v - the speed of advancement of the clearing slab, m / day is safe. Testing of the degassed coal strip is first performed on a single formation, while a degassing zone is formed on another formation. The dimensions of the reference pressure zones and the range of natural degassing zones are determined by known methods. 1 il. (L
