Description
(54) СПОСОБ ВЫЕМКИ ПЛАСТОВ ПОЛЕЗНЫХ ИСКОПАЕМЫХ(54) METHOD FOR EXTRACTING PLASTS OF MINERAL RESOURCES
Изобретение относитс к горной промышленности и может быть использовано прв выемке пластов полезных ископаемых.The invention relates to the mining industry and can be used in the excavation of seams of minerals.
Известен способ выемки пластов полезных ископаемых, включающий опережаю- щую выемку полезного ископаемого в верхней части груди забо .There is a method of excavation of mineral deposits, including a leading excavation of a mineral in the upper part of the chest at the bottom.
Однако в данном способе при частичной разгрузке призабойной части массива полезного ископаемого увеличиваетс шири- на незакрепленных обнажений кровли.However, in this method, with partial unloading of the bottom-hole part of the mineral array, the width of loose roof exposures increases.
Известен способ выемки пластов полезных ископаемых длинными очистными забо ми с разгрузкой забо от напр жений посредством проведени в пласте пред варительных врубов с помощью исполнительного органа, оснащенного резцами.The known method of excavation of mineral deposits by long cleansing holes with unloading of the stress relief by means of pre-cutting cut-outs in the reservoir with the help of an actuator equipped with incisors.
Однако данный способ характеризует с неудовлетворительными услови ми поддержани кровли в призабойном простра стве.However, this method is characterized with unsatisfactory conditions for maintaining the roof in the bottomhole formation.
Целью изобретени вл етс повыше вне устойчивости, кровли.The aim of the invention is to increase the stability outside the roof.
Это достигаетс тем, что преДваритель ные врубы провод т с действующей толш№ной , не превышающей минимальной величины сближени кровли и почвы в течение одного выемочного цикла, причем предварительные врубы при их проведении заполн ют разрушенным полезным ископаемым , например путем направлени движени резцов исполнительнс о органа от усть вруба вглубь массива.This is achieved by the fact that the pre-carving cuts are carried out with a valid thicker one, not exceeding the minimum value of the roof and the ground coming together during one excavation cycle, and the cuts are filled with destroyed minerals, for example, by directing the movement of the incisors from the mouth of the cut in depth of the array.
Сушность изобретени заключаетс ;В следующем.Dryness of the invention is as follows.
