Description

Изобретение относитс к горной промышленности и может использоватьс при комбинированной разработке месторождений полезных ископаемых.The invention relates to the mining industry and can be used in the combined mining of mineral deposits.

Известен способ повторной разработки крутопадаюших рудных залежей в зоне вли ни подземной разработки, включающий выемку горных пород, погрузку и транспортирование горной массы с применением добычных машин, например, экскаваторов или ковшовых погрузчиков flj.There is a known method of redeveloping steep deposits in the zone of influence of underground mining, which includes excavation of rocks, loading and transportation of rock mass using mining machines, for example, excavators or flj.

Однако этот способ не обеспечивает безопасного ведени горных работ в зоне сдвижени горных пород.However, this method does not ensure the safe management of mining operations in the zone of displacement of rocks.

Известен также способ повторной разработки крутопадакшшх рудных залежей в зоне вли ни подземной разработки, включающий последовательную выемку горных пород уступакш, погрузку и транспортирование горной массы 2 .There is also known a method for re-developing steep deposits in ore deposits in the zone of influence of underground mining, which includes the sequential excavation of rocks, the loading, and transportation of rock mass 2.

Такой способ характеризуетс относительно низкой безопасностью ведени горных работ, а также значительными потеp /ra полезного ископаемого.This method is characterized by relatively low safety of mining, as well as significant loss of mineral.

Цель изобретени - повышение безопасности ведени горных работ и более полного извлечени полезного ископаемого из зоны сдвижени горного массива подThe purpose of the invention is to improve the safety of mining operations and more complete extraction of minerals from the zone of displacement of the mountain range under

воздействием подземной выработки.the impact of underground workings.

Это достигаетс тем, что выемку горных впород из зоны сдвижени осуществл ют в первую . очередь со стороны лежачего бока залежи и затем после понижени гор-This is achieved in that the excavation of the mountain in the rocks from the displacement zone is carried out first. turn from the side of the lying side of the reservoir and then after lowering the mountain

вых работ на один-два уступа со стороны вис чего бока залежи с прмош,ью устанавливаемого вне зоны сдвижени драглайна с нижним черпанием и максимальным радиусом последнего не менее половины ширины зоны сдвижени , причем выемку горных пород верхних горизонтов осуществл ют по бестранспортной сх;еме с размещением отвалов за границей карьера.One or two steps from the hanging side of the reservoir is from the prmosh, installed outside the dragline displacement zone with the lower scoop and the maximum radius of the latter at least half the displacement zone width, and excavation of the upper horizons is carried out using the best transport infrastructure; placing dumps abroad career.

На чертеже приведена схема повторнойThe drawing shows a rerun

разработки крутопадающих рудных залежей. Способ заключаетс в следующем. Драглайном 1 с максимальным радиусом черпани не менее половины ширины зоны сдвижени 2, установленном на рабочемdevelopment of steeply dipping ore deposits. The method is as follows. Dragline 1 with a maximum radius of scooping at least half the width of the displacement zone 2 installed on the working

horizon 3, the excavation of rocks from the zone of displacement, primarily from the side of the recumbent side of the deposit 4, is carried out by bottom drawing with preliminary preparation of the working platform by dumping the prefabricated 5. The placement of mining vehicles takes place outside the zone of displacement. Collapsed rocks after, blasting and pre-shaft formation, increase the thickness of the - ceilings 6, reduce the risk of failure, and eliminate emergency conditions. After lowering the mining operations by one or two benches, a similar excavation of rocks from the BHCjnjejX side of the deposit is carried out. When mining the upper horizons, the excavation of rocks is carried out according to a non-transport scheme with the placement of dumps abroad. Claims of Invention A method for redeveloping steeply dipping ore deposits in the zone of influence of underground undermining, including the sequential excavation of rocks by ledges, loading and transportation of rock mass, characterized in that;

f S 3 with the aim of improving the safety of mining operations and more complete extraction of minerals from the zone of displacement of a mountain massif under the influence of underground work, the excavation of rocks from the zone of displacement is carried out primarily from the side of the recumbent deposit and then after lowering the mining operations by one - two steps from the hanging side of the deposit with the help of an out of the dragline sliding zone with the lower scoop and the maximum radius of the latter not less than half of the shift zone width, and the excavation X-rocks of the upper horizons are carried out according to (non-transport scheme with placement of dumps abroad).
