Abstract
The present invention relates to a mining method by cutting ore breakdown and dry filling artificial ore pillars, which belongs to the field of mining. The present invention is suitable for jade ore deposits of any inclination angle and any thickness. The present invention is characterized in that artificial ore pillars adopt cutting ore breakdown; a bumper pad is arranged on the lower side of ore breakdown; a special ore support sledge can be used for transport. The present invention has the advantages that the ore recovery ratio can be enhanced from 80% to 95%; the finished product ore yield rate can be enhanced from 20% to 85%; the finished product ore can be enhanced to 1 to 2 grades; the economic value of the mining quantity can be enhanced to more than ten times.
Description
Technical field
The invention belongs to field of mining, particularly a kind of underground mining method.
Background technology
Jade is the important source material material of high-grade handicraft, the underground mining of present jade deposits, generally adopt shallow-hole shrinkage stoping method, miner's skill because the technology arrangement of this mining methods and explosion fall, the jade ore deposit rate of recovery is hanged down reach because of producing many secondary interstices in the jade material material piece of extraction, again through felling and transporting collision mutually between the ore in the process, make the further subject to severe risks of damage of globality of the jade material material piece of extraction, cause the output capacity in jade finished product ore deposit low, the grade in finished product ore deposit is low, has a strong impact on the economic benefit of jade ore deposit exploitation.
Summary of the invention
Purpose design of the present invention is a kind of to improve ore recovery ratio and the secondary interstice of extracted ore is reduced as far as possible, in the process of felling and transporting, do not destroy extracted ore piece globality as far as possible, thereby make finished product ore deposit output capacity, all high mining methods of finished product ore deposit grade.
The present invention realizes like this, be divided into several nuggets along orebody trend, in the ore body lower wall country rock of each nugget, drive ore drawing courtyard 1 and pedestrian's vent (-escape) raise 2, and the upper end of two courtyards is linked to each other with return aircourse 3, the lower end links to each other with haulage drift 10, rim orebody trend and under ore body near the cutting gallery 9 of prospect outside arteries and veins of ore body pick a cutting gallery 8 and a vertical orebody trend, drive a stope connection roadway 4 every 5 meters to ore body 13 at pedestrian's vent (-escape) raise 6, contact ore body end at the stope connection roadway, drive an arteries and veins near the ore body lower wall and cut courtyard 5 outward, stopping sequence routinely, in vertical direction back production successively from lower to upper, begin to the 1 direction back production of ore drawing courtyard by pedestrian's vent (-escape) raise 2 in the horizontal direction, be that the secondary interstice that makes the lump under adopting reduces as far as possible, adopt and cut the ore deposit, be exactly to adopt intensive parallel hole and coupling charging not at place, the non-scope of freedom,, adopt not powder charge emptying aperture to carry out the Cutting Control explosion ore deposit that falls in junction, two cross sections; Damaged when ore falls when falling the ore deposit for reducing is provided with cushion pad below the ore deposit that falls; The lump that cutting falls, the special year ore deposit vehicle of packing into is transported to haulage level through ore drawing courtyard 1 usefulness winch 12; The goaf is with adopting with filling, and casting resin 14 is a waste wool stone, as the horsestone in the mineral ore, non-ore rock, cut the rock of group's wall; For improving ore recovery ratio, do artificial foundation 2 and artificial wall 11.
The present invention can make ore recovery ratio bring up to 95% by 80%, and finished product ore deposit output capacity brings up to 85% by 20%, and 1～2 grade can be improved in the finished product ore deposit.

The specific embodiment
Mining method by cutting ore breakdown and dry filling artificial ore pillars, be divided into several nuggets for 30～50 meters along orebody trend, 20～60 meters of Duan Gaowei, in the ore body lower wall country rock of each nugget, drive ore drawing courtyard 1 and pedestrian's vent (-escape) raise 2, and the upper end of two courtyards is linked to each other with return aircourse 3, the lower end links to each other with haulage drift 10, rim orebody trend and drive the cutting gallery 9 of cutting gallery 8 and the vertical orebody trend of prospecting outside the arteries and veins near ore body under ore body, drive a stope connection roadway 4 every 5 meters to ore body 13 at pedestrian's vent (-escape) raise 6, at the contact ore body end of stope connection roadway 4, drive an arteries and veins near the ore body lower wall and cut courtyard 5 outward.Stopping sequence in vertical direction back production successively from lower to upper, is begun by pedestrian's vent (-escape) raise 2 in the horizontal direction routinely, and to ore drawing sky and 1 direction back production, the face height is 2～2.5 meters.The secondary interstice of the lump under adopting being reduced as far as possible, adopt the cutting ore deposit that falls, is exactly to adopt intensive parallel hole and coupling charging not at place, the non-scope of freedom, in junction, two cross sections, adopts not powder charge emptying aperture to carry out the Cutting Control explosion ore deposit that falls; Damaged when ore falls when falling the ore deposit for reducing, placing old tire below the ore deposit that falls is cushion pad; The lump that cutting falls, the holder ore deposit sledge of packing into special, the winch 12 in ore drawing courtyard 1 is transferred to haulage level; The goaf is with adopting with filling, and casting resin 14 can cut the rock of group's wall for horsestone, non-ore rock, insufficient section in the mineral ore; Be to improve ore recovery ratio, artificial sill pillar 2 can be made steel concrete, and artificial wall 11 can make concrete.
