Abstract
FIELD: mining. SUBSTANCE: method for driving mine slopes along seam slope includes driving a number of parallel workings and filling them with cast solidifying mixture. First, three subsidiary working slopes are driven through coal. Spacing between the working equals design width of main workings. Then the workings are filled with cast solidifying mixture. On completion mixture solidification main coupled workings are driven. EFFECT: higher productivity. 1 cl, 9 dwg

Изобретение относится к горной промышленности. Способ проходки спаренных наклонных шахтных выработок по падению пласта, включающий проходку ряда параллельно расположенных выработок и заполнение их литой твердеющей смесью, отличается от известных способов тем, что сначала проходят три вспомогательные наклонные выработки по углю на расстоянии между ними, равном проектной ширине основных выработок, затем заполняют их литой твердеющей смесью, после ее затвердевания осуществляют проходку основных спаренных выработок. 9 ил.The invention relates to the mining industry. The method of driving paired inclined mine workings over a dip of the formation, including driving a series of parallel workings and filling them with a cast hardening mixture, differs from the known methods in that three auxiliary inclined workings in coal pass at a distance between them equal to the design width of the main workings, then they are filled with cast hardening mixture, after its hardening, the main paired workings are drilled. 9 ill.
