Double the lead and zinc production in Japan kamikaze
Rate of only drilling Berry 300m,uggs ireland, but also the life of drill stem from the 600m ~ _ long to 1lOOm above. It is the strength of these Jiangxi l ~ 0 \Sub-Tu. Stratified filling fruit market competition law high 5m. l length 20m, each blast mine to see 1050t. Long with the propeller of a 3.5 ~ 4.5m of T ~ imrockMinimatie drill rig drilling bath. Dump bucket B. blasting Envoy Scrapers 5ms loading and transport. There are two remote control system installed by the scraper. 1987, the central cabinet hole mine blasting system used. In recent years, a large mining dump trucks ANFO charge and electric charge self-propelled vehicle greatly improves production efficiency. Another. A Chiang interesting things that are team system. In this regard, drilling, charging, loading and filling jobs in each sub-song special operations team consisting of workers to complete each team is responsible for 15 ~ 2O a face, which enables the device to at least the parking time. Each team usually has 3 sets of self-7g / f Zhou 7, lifting agricultural Angeles pus; '} tg mother. 3 wide-fill mining method reduces cement mining and metal loss in recent years means Xiajun Wu Wang. Fill mining method with cemented study the growing amount of mining, due to depleted ore containing cement the adverse effects on the flotation process, mineral processing process is increasing the amount of metal loss. So far,ugg boots ireland, from the limited perspective of this adverse effect, in fact, not to control the body and the plastic filling material filling mantis nature of the problem in-depth research. Gob Filling with mining mining law, the poverty reduction in the amount of pure ore is mixed with useful minerals as a qualitative change in the material could not achieve the desired results. Proved useful in the beneficiation process of recovery of both minerals and the dilution rate, but also with the group with cemented filling families about Viagra. There are several ways to reduce metal loss in the dressing process. Such as the use of impact toughness of cemented backfill filling material I in the contact zone with the ore mining} by controlled blasting ore in filling the interface with the quarantine measures taken to avoid the blast wave of the destruction of filling the role of 'filling material composed of , used little impact on the process of dressing or even beneficial to filling material. . : In order to reduce ore dilution caused by filling material, we must control the structure of cavity filling end - to improve their ball bad to accommodate. Cement filling material caused by ship ore dilution rate) and the filling material toughness (u) exponentially. If 0.5 ≤ \, The lgTil7 ~ 0.2 for the design of the limbs Results Jie Keli mine filling material composition of the cement filling material over the ore project} dilution rate (0 ~ l2) and the impact toughness increases from zero to 5.0MJ / m when the relationship. Research shows that when filling the toughness by the Division L0MJ / m. Reduced to zero pairs, the loss of base ore dilution from 2 to 12% which will increase the rate of metal loss dressing. Filling compound in the cement, aggregate granule added flexibility can reduce the cement and bone of a Concrete Structure surface of the two local stress concentration,ugg stiefel, which can effectively inhibit the formation of fractures in hanging scroll filling process and filling in the damage. The grain size by adding the inhibitory effect of bone on the stress concentration is conducive to cementing agent (cement, slag and ash, etc.) and the thickness of the aggregate dispersion of JI (ceramic. Jane Qu rock, vermiculite, slag, etc.) _ the Wei block size to adapt the degree to analyze ore cemented restorations Jieke Li Yuan instantaneous structure, shortage of cement and aggregate particles case, the amount of control structure must be the formation of the cement. Recommended static load space rent increase under dynamic load filling cut-off strength and good dispersibility additives. In this case, the restorations can be calculated Guo impact toughness and compressive strength, if 1. O ≤ # ≤ 6.0Mpa, the a28-A ・. 3MJ / m ~. . :. Where, A and n a partial inhibition of the stress concentration factor to add material experience. Thermal power station ashes tA = 0.81, n = 1.22, calcium mineral note lA = 3. J-9) n = 0.25) finely ground rock lA1.82, n0-26 depends on the optimal set by Xi Tian plus add l materials under deformation process of filling for the rejection mechanism. Jump in the cavity end filling compound outside the mattress plus Tam Xinjiang particles aggregate New Zealand rock aggregates,GHD glätteisen günstig, can form a line drill rig bone,ugg botas, 2 shovel away machines and 1 set charge car. An anchor and shotcrete are also done by the team, digging in the jet way before the exposed area of concrete more than 20% need to install the anchor loom, each team is not ready to bolt if the mine so much to maintain existing production capacity, sufficient reserves of mine has 8 fully capable of mining to the next century. Kamioka mine management has recognized that in order to maintain the competitiveness of mine, this mountain still need to further automate the mining and use of the cup moving equipment.
