Abstract
The invention discloses a high-dipping medium thick ore body mining method. Filling is executed in an upward horizontal segmental manner. A middle section of an ore body is divided into five segmental flat alleys (1) according to a vertical height direction; a steel wire rope and a pipe seam anchoring rod are arranged in a goaf of a first segmental flat alley (1-1) of the middle section; a paste body, which is formed by adding cement into concrete C25 or tailings and serves as a cemented filling body (4), is used for filling the goaf; dry-type filling bodies (3) are filled in second, third, fourth and fifth segmental flat alleys (1-2, 1-3, 1-4 and 1-5) of the middle section; a studding (5) reserved in a mining field is replaced by an artificial rubble concrete supporting column (6). The high-dipping medium thick ore body mining method is simple in construction, and can be used for effectively improving the ore recovery rate and the safety and reliability of a mining field.
Description
Technical field
The present invention relates to a kind of mining methods, especially for going up to formula horizontal fragmentation filling method of high-dipping middle thickness orebody.
Background technology
The mining of high-dipping middle thickness orebody, sublevel open stope method and the dry filling methods of adopting are carried out back production more always, and each stage casing of sublevel open stope method, segmentation need be stayed and establish a large amount of fore-sets, studding, and poor stability; The dry filling method stope all adopts the rubble dry stowing, withstands during in order to ensure the back production of following stage casing and protects the top, and each stage casing need be lost the ore bed of a segmentation at least, ore recovery rate is low, and dry stowing can not make goaf filling connect the top, and filling effect is poor, and security reliability is poor.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of high-dipping middle thickness orebody mining methods are provided, effectively improve the ore recovery rate of stope, and guarantee that stope is safe and reliable.
Technical scheme of the present invention is: a kind of high-dipping middle thickness orebody mining methods, to the filling of formula horizontal fragmentation, according to the height that hangs down stope is divided into a plurality of stage casings earlier in the employing, is divided into five slice drifts by vertical height in each stage casing then, since first slice drift, upwards exploitation piecemeal; After first sub-level drift stoping in this stage casing finishes, arrange wire rope and pipe seam anchor bar in the first slice drift goaf, the sealing stope is imported and exported, and C25 concrete or tailings is added the lotion that cement makes again and is fills up to the goaf as cemented fill; Second and third of stage casing, four, five slice drifts all adopt the filling of dry stowing body.
The vertical height of the slice drift in the described high-dipping middle thickness orebody mining methods equates, and is 12 meters.
During back production, the studding in the back production dry stowing stope at first, i.e. first back production second and third, the studding in four, the five slice drift stopes, build the artificial shore supports of rubble concrete goaf then by laying bricks or stones.
The filling method that the present invention adopts dry stowing and consolidated fill to combine to underground goaf, construction is simple, and stope is safer, and reliability is higher.The ore bed of a segmentation is avoided losing in the artificial false top of the cemented fill of first slice drift during as next stage casing stope mining.Stay the studding of establishing to adopt the artificial pillar of rubble concrete to replace to stope, effectively improve ore recovery rate.
Description of drawings
Fig. 1 is ore body structural representation of the present invention;
Fig. 2 is the section A-A schematic diagram.
The specific embodiment
As shown in Figure 1, a kind of high-dipping middle thickness orebody mining methods, in the employing to the filling of formula horizontal fragmentation.Ore body 7 is divided into a stage casing according to 60 Mi Chuigao in the stope, is divided into five slice drifts 1 by 12 meters of vertical heights in this stage casing.Slice drift 1 is arranged in 15 meters of bed top along ore bed, adopts accurate ramp 2 and is arranged in 40 meters of bed top.
After the first slice drift 1-1 back production in stage casing finished, behind layout wire rope and the pipe seam anchor bar, the sealing stope was imported and exported, and the C25 concrete is fills up to the goaf as cemented fill 4 in the first slice drift 1-1 goaf.The artificial false top of the cemented fill 4 of the first slice drift 1-1 in this stage casing during as next stage casing stope mining.In the stage casing second and third, four, five slice drift 1-2～1-5 all adopt 3 fillings of dry stowing body, the stope of dry stowing, at first the construction crossdrift by the slice drift 1 of bed top enters stope, enter the studding of reserving in the first back production stope behind the stope 5, build the artificial pillar of rubble concrete 6 after studding 5 back production by laying bricks or stones and support goaf top plates, after the ore of rooming again.
