The present application relates to the technical field of
mining engineering, and discloses a kind of gently inclined extremely thin lode reserved strip column horizontal
deep hole mining method, by gently inclined extremely thin lode reasonable division ore block, top column, bottom column and strip column are reserved, both can rely
on column body support roof, improve stope stability, also can be separated by strip column room, optimization
stoping layout, simultaneously adopt horizontal
deep hole differentiating charge blasting, with
cutting up mountain as compensation space double-side retreat mining, initial section uses continuous charge, after blasting, connect each room, guarantee ore pass smooth, subsequent non-continuous charge is used, avoid the area where top column, bottom column and strip column are located, only lateral caving ore is implemented to room section, realize accurate ore
stoping, reduce
dilution rate, and top column and bottom column reserved replace traditional artificial filling
retaining wall, only a small amount of
retaining wall is needed to build, save cumbersome procedure, greatly improve efficiency and reduce cost, simultaneously simplify process, improve
operation safety, realize extremely thin lode safe, efficient, low-cost mining.
