Abstract
Изобретение относитс к горному делу и предназначено дл открытой разработки полезных ископаемых. Цель - исключение затрат на транспортировку потенциально плодородных пород путем одновременной отсыпки и подготовки отвала к рекультивации . Дл этого на слабое основание гидроотвала отсыпают заходку 2 из коренных пород . Затем параллельно заходке 2 отсыпают заходку 3 такой же высоты, оставл промежуток между их нижними бровками . Рассто ние L между заходками 2 и 3 определ ют по формуле L ctg a (H32+khOCH2 J : (khocH-Мрек), где Н3 - высота заходки, м; М0сн - мощность слабого основани , м; Ьрек - мощность ре- культивационного сло , м; а - угол откоса отвальной заходки, град; k - коэффициент, учитывающий потери грунта в межкусксвом пространстве заходки, ,7-0,8. Отсыпка заходок 2 и 3 сопровождаетс вытеснением пород слабого основани из-под заходок в промежуток между ними. Отсыпанную заходку 3 развивают в направлении ранее отсыпанной заходки 2 до смыкани их нижних бровок. При этом вытесненные породы слабого основани разравнивают по поверхности отвала, формиру рекультивационный слой. 3 ил.The invention relates to mining and is intended for open-cast mining. The goal is to eliminate the cost of transporting potentially fertile rocks by simultaneously dumping and preparing the dump for recultivation. To do this, pour into the bedrock of 2 bedrocks on the weak base of the water dump. Then, parallel to the entry 2, pour off the entry 3 of the same height, leaving the gap between their lower edges. The distance L between visits 2 and 3 is determined by the formula L ctg a (H32 + khOCH2 J: (khocH-Mrek), where H3 is the height of the approach, m; M0sn is the power of a weak base, m; , m; a is the angle of repose of landfill, hail, k is the coefficient taking into account the loss of soil in the interpossal space of the stopovers, 7–0.8. Dumped gate 3 develop in the direction of the previously dumped gate 2 to the closure of their lower edges. s breed weak base is spread over the surface of the blade, forming a layer of remediation. 3 yl.
