Abstract
The invention discloses a room-and-pillar major-diameter longhole inverted-step-like segmented lateral caving subsequent filling mining method for a steeply-inclined medium-thick orebody and gently-inclined and inclined extremely-thick orebodies with steady surrounding rocks at upper and lower panels. The method is characterized in that: an orebody is divided into panels, then the panels are divided into continuous single-stage stoping units, and mining is carried out by using a stoping sequence of stoping one unit every other unit, i.e., mining a room at first and a pillar next; when mining a room, a V-shaped trench bottom structure is employed, a longhole drilling chamber is arranged at the upper part of stope, bar-shaped pillars are left to support the top plate of the chamber, a down-the-hole drill is used for drilling rocks, an explosion mode of light section VCR method underholing inverted-step-like lateral caving with a common emulsion explosive is employed, access roads towards the room for ore removal are arranged in the pillars, and cemented roof-contact filling is employed; and during stoping of the pillars, access roads for ore removal are dug towards the pillars in cemented bodies in the room, a stoping manner for the pillars is identical to that for the room, and non-cemented filling with tailings and waste is employed. The method provided by the invention has the advantages of high security, a low production cutting ratio, great production capacity, low operation cost and small loss and dilution of resources.
Description
Technical field
The invention belongs to the mining technique field, relate to a kind of house column type large diameter, deep borehole scalariform segmentation lateral caving afterwards filling mining method of falling from power, the method mainly is applicable to thick above and gentle dip～inclination utmost point big thick ore body in the firm high-dipping of upper lower burrs country rock.
Technical background
Thick above and gentle dip～inclination utmost point big thick ore body great majority employing sublevel open stoping afterwards filling mining method or traditional " VCR " method exploitation in the at present high-dipping.The sublevel open stoping afterwards filling mining method need tunnel many segmentation haulage ways, rock drilling ore removal crosscut, slot raise, adopts accurate cutting engineering quantity large; Use upward to fan shaped medium length hole during the mineral building back production, make after the explosion rib of ore pillar uneven, integrality is destroyed, and causes the pillar recovery worsening condition, simultaneously, uses the common boulder yield of scallop hole to increase, and has strengthened stope secondary blasting workload, has reduced ore removal efficient; Traditional " VCR " method exists each blast charging hole count too much, and stope exposure area is too large, adopt and fill the defectives such as uneven.
Summary of the invention
The technical problem to be solved in the present invention is for thick above and gentle dip～inclination utmost point big thick ore body in the firm high-dipping of upper lower burrs country rock, proposed a kind of safe, adopt and cut than the house column type large diameter, deep borehole low, that production capacity is large, mechanization degree is high, operating cost is low, the poor damage of resource the is little scalariform segmentation lateral caving afterwards filling mining method of falling from power.Technical solution of the present invention is as follows:
(1) the ore body pillar is divided the panel, division stage continuous stoping unit is in the panel in, the stopping sequence of implementation " adopting every " the room post of digging up mine again of namely digging up mine first;
(2) the stage stope bottom structure mainly comprises the ore removal crosscut, ore removal route, rock drilling Ji Kuang crosscut; Reach to fan shaped medium length hole at rock drilling Ji Kuang crosscut central authorities construction slot raise simultaneously, form " V " type moat ditch;
(3) stage stope top is drilling chamber, and message post in the middle of the chamber, ore pillar drilling chamber also need to stay the semicolumn roof supporting near the both sides obturation;
(4) downward Drilling large diameter, deep borehole in drilling chamber, stope adopt the blasting method of " light section VCR method grooving---high sublevel fall from power scalariform lateral caving ", by ore caving interval, height controlled blasting scale;
(5) shrink ore removal: control ore drawing in stope during the scalariform lateral caving explosion of falling from power, carry out the shrink explosion, each the required compensation space height of the complete explosion of ore removal supports ore deposit rock or obturation with the quick-fried ore that falls;
(6) strengthen ore removal: the stope explosion is complete, and tissue is strengthened ore removal, shortens stope dead zone open-assembly time as far as possible, makes stope be able to as early as possible filling;
(7) the classified tailings adhesive bond top tight filling of different proportionings, the non-adhesive bond filling of the complete rear main employing tail stone of pillar recovery are adopted in the mineral building back production after complete from bottom to top.
Beneficial effect
(1) stoping safety is high
Stope rock drilling, powder charge, explosion, ore removal all under prop, not operation in the goaf; Blasting method adopts the scalariform segmentation lateral caving of falling from power, and stope is formed stress arch force structure, is conducive to STOPE STABILITY.
(2) adopt accurate cutting engineering quantity low
Employing stage back production unit, accurate engineering quantity is adopted little in the slice drift of need not constructing, sublevel drilling ore removal lane; Adopt " light section VCR method " directly explosion formation cutting groove, the cutting engineering quantity is little.
(3) production capacity is large
Adopt the stopping sequence of " adopting one every one " to make to adopt between the back production unit cut, supporting, rock drilling, Luo Kuang, ore removal, filling procedure parallel operations and be independent of each other, realize adopting simultaneously filling balance, production capacity is large.
(4) the resources loss rate of dilution is low
Smooth Surface Blasting Technology is adopted on mineral building stope border, avoids explosion damage and cutting impact on ore pillar, keeps smooth smooth crag, during Pillar mining, and both sides cemented fill roof supporting, the loss and dilution rate is low.
(5) mining cost is low
The single proportioning filling that changes mineral building be polygamy than filling, save filling cost; Adopt the fall from power blasting method of scalariform lateral caving of large diameter, deep borehole high sublevel, mining area production capacity improves greatly, the corresponding reduction of mining cost.
