Definitions
- the invention relates to incorporating, in the underground exploitation methods by sinking blocks / panels, a continuous ore management system, which will be installed in the Transportation Galleries (GT) of the Production Level and in Transportation Sub-levels, located a few meters below the GT.
- GT Transportation Galleries
- the deep mineral bodies are constituted by healthy rocks - practically unaltered -, impermeable, with few natural fractures; geometrically very competent (harder and more resistant), called: hard rock or primary ore.
- hard rock or primary ore The main issue is the new problems that are emerging as mining exploitation progresses to greater depths, because the fragmentation of the ore is increasingly thick.
- Many colpas have a size of several cubic meters. This forces to build more extensive and expensive underground infrastructure and to use inefficient material handling systems.
- the operating systems employ large fleets of equipment, cargo and transportation; they operate with prolonged, intermittent and alternative cycles, frequently exposed to long-lasting interference, caused by:
- Each unit of LHD, with diesel engine, to operate requires an area extension of over 10,000 m 2 . In that space, its operation, for reasons of ventilation, is mutually exclusive with other LHD units, preventing extracting greater tonnage per unit area.
- Each LHD has a performance, depending on the distance to the dumps and the granulometry of the mineral, very low, from only 4,000 to 6,000 tm / day. Effective operational time rarely exceeds 10 hours per day.
- the sinking rate.- refers to the speed with which the mineral in situ, once undermined, as a result of the extraction of ore from the Extraction Points, is transformed into broken ore, fragmentation that should be increased as much as feasible. It will be achieved by an effective pre-conditioning in situ of the rock mass, fracturing and fragmenting it intensely.
- the PANZER has been the transport equipment selected to be applied in the mining of primary rocks.
- the equipment is made up of a set of elements manufactured with a high level of machining and therefore a high cost.
- FIG. 1 Corresponds to a section along the axis of the Transport Gallery (GT), in the Production Level. There the following components stand out:
- Purpose of the invention It is related to the design of one of a continuous system of handling and separation by size of the extracted ore, constituted by: a heavy ore trawler (TA) transport equipment with stationary grills - both located in the Galleries of Transport (GT) of the Production Level -, and a conveyor belt 13 for fine ore, installed in a Transport Sub-Level 12 -, located a few meters below the Production Level -, with such an arrangement, that allows to increase the rate Mineral extraction through greater global transport capacity and higher crusher performance.
- TA heavy ore trawler
- GT Galleries of Transport
- a conveyor belt 13 for fine ore, installed in a Transport Sub-Level 12 -, located a few meters below the Production Level -, with such an arrangement, that allows to increase the rate Mineral extraction through greater global transport capacity and higher crusher performance.
- the TA consists of a series of metal drag bars 5, rectangular, located perpendicular to the axis of the GT 18, of the Production Level, positioned at the edge and regularly spaced (staggered).
- the TA carries the ore it receives from the feeder extractors 2 located at the Extraction Points (PE) 1.
- the drag bars are joined together by their ends by chain links 6, as endless chains. Through these two chain lines, by traction, the forward movement of the drag bars is transmitted.
- a part of the TA operates on the floor of the GT of the Production Level and it is there that it receives the mineral feed extracted from the EPs. It transports the ore, by drag to one end, where it feeds a crushing equipment 14 or a haulage. The part of the TA that returns empty makes it suspended on the roof of the GT.
- the floor of the conveyor consists of metal plates 8, seated on a concrete radier 7, and fixed on firm rock by means of expansion bolts.
- the traction lines 6 are confined in metal guides type U 16, which are fixed in firm rock, by means of expansion bolts. In the air return, the guides are anchored, with expansion bolts to the walls and ceiling.
- two pairs of wheels 3 and 4 are placed, supported on horizontal axes and anchored to the floor, which channel the return of the conveyor.
- the front wheels 3 are driving, and drive the TA by traction, engaging with the chains.
- Screening scheme It consists of the installation of several Stationary Grills 9, on the floor of the TA, composed of bars aligned with the axis of the GT, spaced apart with an opening such that they allow to pass that size of mineral that the equipment of crushed, fed by the TA, delivered as a product.
- the Stationary Grills will be located between the PE 1, will unload the ore of small size in short pikes 10, connected to a Sub Level of Transport (SNVT) 12, in which a Conveyor Belt 13 will be installed that will take it to its destination.
