Dongguashan Copper Mine is located in the east of Tongling, Anhui Province, China, and the deposit is in the deep part of the Shizishan copper mining area. This mine is the first hard rock metal mine in China, with a mining depth of up to several kilometers and prominent susceptibility to rock burst.
The rest of the paper is organized as follows. Section 2 presents the implementation details of automatic classification of microseismic signals based on MFCC and GMM-HMM. In Section 3, we test our proposed method using the field data recorded in an underground copper mine. Finally, Section 4 summarizes the main conclusions.

Aug 01, 2017nbsp0183321. Introduction. Due to an increasing demand for mineral resources in China, numerous metal mines, such as the Hongtoushan copper mine, the Dongguashan copper mine, the Jiapigou gold mine, the Sanshandao gold mine, the Fankou lead-zinc mine, the Linglong gold mine, and so forth, have operated at depths exceeding 1000 m .Deep mining inevitably creates an increase in and.
201321-20135-31, Dongguashan Copper Mine had tested this new material semi-autogenous mill liner. The results show that normal manganese steel mill liners can work 30 days the new design mill liners can work 70 days, more than 2 times working life.
In this study, the microseismic data of Dongguashan Copper Mine before December 13, 2017, are selected as the training data sets. Four types of events, rock mass rupture events, blasting vibration events, rig drilling events, and electromagnetic interference events, are manually labelled by experienced experts. The total number of the events is 1400, with each type of 350 events.

Dongguashan copper ore is one of a complex copper sulphide ores containing various metal minerals in Tong ling area. In this paper, in order to simplify the complexity of traditional lime process, the process of Cu-S bulk flotation-regrinding-separation is discussed and exploited. A good quality of Cu concentrate and S concentrate are obtained respectively after Cu-S separation by using calcium hypochlorite as depressant. A good separation results are derived through this process, and high efficiency of calcium hypochlorite used as depressant and feasibility of the process are confirmed.

For limiting the damage range caused by explosive shock loads in vertical crater retreat VCR mining, the blasting damage characteristics of surrounding rock were studied by two methods numerical simulation and ultrasonic testing. Combined with the mining blasting in Dongguashan Copper Mine of China, the VCR blasting shock characteristics under different conditions are obtained by using LSDYNA.
The mine was put into trial production. The designed production rate is 5000 td, with two processing streams composed of a 2500 td of Lead-Zinc system and a 2500 td of Copper-Tin system. The underground mine uses a main ramp development system, the sublevel open stoping and a bottom-up cut and fill method. A.

Distribution and occurrence characteristics of copper minerals.
1 porphyry copper deposit. The main minerals are chalcocite and chalcopyrite, the copper grade of 1 1.5, associated minerals are pyrite, sphalerite, molybdenite, copper nickel ore and gold comprehensive. Both the distribution of Chinas Shanxi, Jiangxi Dexing, Hebei Tongkuangyu Xiaosigou etc.
2 layered copper deposit. The main minerals are chalcopyrite, chalcocite, bornite, malachite, azurite, malachite and silicon, rare tetrahedrite, mineral mainly galena, sphalerite, pyrite, limonite, hematite, calcite, quartz and barite etc.
3 pyrite type copper deposit. Pyrite ore, more than 95 of the total, which is associated with chalcopyrite, sphalerite. In addition to containing gold, silver, lead, selenium and other coexisting elements, gangue minerals are sericite, chlorite, quartz etc.
4 the rock type copper deposit. Mainly composed of gossan, malachite, chalcopyrite, the lower part is often a secondary enrichment zone composed of dense chalcocite and soot like chalcocite. Such deposits are widely distributed in China, such as Anhui Tongling, Hubei Daye, Jilin, Liaoning, Hebei Huatong Tianbaoshan Shou Wang Fen etc.
5 vein copper deposit. The main ore minerals are pyrite, chalcopyrite, sphalerite, galena, followed by tetrahedrite, bornite, chalcocite, pyrrhotite, gangue quartz and calcite, barite, and siderite, sericite, chlorite, Rhodochrosite etc.
In addition, there are sandstone type copper deposits, copper nickel sulfide deposits and andesitic basalt copper deposits.
In the world has proven the total reserves of various types of copper ore, porphyry copper accounted for more than 60, sandstone copper ore accounted for 25 26, containing copper pyrite accounted for more than 5, other types of copper accounted for less than 10.
The beneficiation process changes flotation of copper sulfide ore varied, summed up mixed flotation, flotation, flotation etc., some flotation flotation, the rapid distribution of flotation, flotation, mixed flotation, asynchronous mixed flotation etc The development of new mineral processing technology is mainly based on the fast, early sowing, early lost in principle, more crushing and less grinding, asynchronous flotation, ramified flotation, electrochemical control flotation process control and originpotential received extensive attention and application.
Flotation of copper oxide ore flotation method includes direct and indirect flotation method, direct flotation method is mainly used for processing the mineral composition is simple, not complex properties of copper oxide ore indirect flotation refers by adding curing agent to oxidation of copper sulfide ore, and then use the ordinary copper sulfide flotation flotation agent, is added to the main ore processing technology section, the method is high demand for curing, curing effect will have a direct impact on the effect of flotation of sulfide ore.
