Description
Изобретение относитс к горной промьшшенности и может быть использовано при проведении горных выработок по пластам калийных месторождений , опасным по динамическим влени м и имею1иим в непосредственной кровле (почве) пласта пластичные горные породы.The invention relates to the mining industry and can be used when carrying out mine workings on seams of potash deposits dangerous for dynamic phenomena and having plastic rocks in the immediate top (soil) of the seam.
Цель изобретени - псшьшение безопасности работ и скорости проведени горных выработок за счет улучшени их устойчивостисThe purpose of the invention is to increase the safety of work and the speed of mine workings by improving their stability.
Способ осуществл ют следующимThe method is carried out as follows.
образом. - in a way. -
Проходческий комбайн оборудуютHeading machine equip
устройством (например, врубовой машиной ) , позвол ющим создавать разгруa device (for example, a cutting machine) allowing the creation of
зочную щель высотой, превышающей мощность непосредственной кровли (почвы) пласта.a cold gap with a height exceeding the thickness of the immediate roof (soil) of the seam
Одновременно с проведением горной выработки комбайном образуют разгрузочную щель длиной в 1-3 раза большей ширины оставл емого по ее длине целика. Затем проход т только выработку , а в кровле (почве) по длине разгрузочной щели оставл ют целик породы шириной, равной не более ширины кровли выработки. После этого одновременно с проведением горной выработки образуют разгрузочную щель указанной длины, снова оставл ют целик породы и так далее до окончани проведени выработки.Simultaneously with the mining operation, the combine forms a discharge gap 1-3 times longer than the width of the rear section along its length. Then, only the excavation is made, and in the roof (soil) along the length of the discharge gap, the pillars of the rock are left with a width equal to no more than the width of the excavation roof. Thereafter, simultaneously with the mining operation, a discharge slot of the specified length is formed, the pillar of the rock is left again, and so on until the completion of the mining operation.
