Description
Technical field
The present invention relates to a kind of mining methods technical field, specifically wall type allwork hydraulic column gib is afterwards filled
Fill out method.
Background technology
Shuiyindong gold mine is located at the forts approximately EW Hui Jia anticline eastern section, is Xingren~Anlong gold of Yangtze paraplatform Margin of Southwest
Output region in " Carlin Trend " gold deposit on mine belt, Shuiyindong gold mine 1100m or more can adopt using ore amount 69.63 ×
104t, 6.72 × 10-6 of average grade, amount of metal 4679kg, 1100m~1000m can adopt using ore amount 445.56 ×
104t, 4.5 × 10-6 of average grade, amount of metal 20050kg, mineral deposit is based on magma bound type, is supplemented by breaking type compound in area
Blind deposit, in category-low temperature hot liquid " Carlin Trend " gold mine, ore body in stratiform, like stratiform, occurrence is consistent with the attitude of rocks, inclination angle
5 °~10 °, thickness is thin for tool, grade is rich, walk tool undulation upwards, incline eastwards not, the spy that spatially multiple ore bodies are overlapped up and down
Point, mining area are the part in the anticline geohydrologic unit of the forts Hui Jia, under natural endowment in area in water-bearing layer underground water supply
Including two aspects：First, vertrep, second is that the lateral runoff from upstream aqueous layer is fed, exposure stratum is essentially in area
Night youth organizes marl, the mud stone of first segment, and landform is based on hilly and mountainous land, and it is bad to ooze condition under Atmospheric precipitation, but on mining area,
Downstream water-bearing layer distribution area is big, therefore, the recharge laterally from upstream be area in the important Source Of Supply of underground water, water-bearing layer by
After supply, underground water outside horizontal runoff discharge area, becomes the supply source in downstream water-bearing layer, only superficial part underground water is in area from West to East
Interior cheuch is discharged earth's surface in the form of Junichiro Koizumi, and mature fault in area, the development in tectonic joint crack, rock stratum crack in layer destroys
The integrality of rock stratum becomes the channel of underground water water-filling, and exploitation, which causes water producing fractures also, can become the channel of underground water water-filling, water
The literary medium complexity of geological conditions, rock stratum is bedded rock in mining area, and based on clastic rock and Impure Carbonate Rocks, engineering
Matter type is sedimentogenic lamellar type, and according to the lithology of rock stratum, mechanics index of physics, ground can be divided into loose rock in area
Group, hard rock group and soft rockmass group three classes engineering geology rock group, ore body are in anticlinal nucleus, and the attitude of rocks is more gentle, in order to
Adapt to local geological conditions, it is necessary to propose that a kind of wall type allwork hydraulic column gib afterwards filling method carrys out quarry
Body.
