·The change of coal mining equipment in the whole industry chain is the main means to solve the environmental impact during the construction period The results point out that gangue and mine engineering are the most influential processes among the 18 midpoints If the enterprise wishes to reduce the toxicity of the water the control of
·Coal mining is accompanied by the discharge of solid waste such as coal gangue and the control of mining pressure and surface the green development of coal mines will be an
·Filling mining technology is a feasible and effective means to build a green mine and protect the environment In order to investigate the overlying rock movement law of gangue filling mining under the condition of no support for thick coal seams this paper takes the Sima mine as the research object and determines the relevant parameters of rock mechanics
·For more than a century flotation has been a widely adopted technique in mineral processing to separate valuable minerals from gangue It is an intricate process however that is influenced by an array of variables including chemistry such as reagents and pulp conditions equipment such as cell design agitation and air flowrate and operational factors
·Our team addressing the issue of existing coal gangue sorting equipment not being compact enough for the narrow underground mine spaces designed a compact coal gangue sorting device suitable for underground chamber sorting Zhao et al 2022c This device includes a conveyance system a sieving system and a coal gangue sensing sorting system
·The two primary mining methods used for nickel extraction are 1 Open Pit Mining Open pit mining is the most common method used for nickel mining especially for large near surface deposits It involves the excavation of the ore body using heavy equipment and machinery such as excavators haul trucks and drills
·Method The equipment integrates mining operations conveying operations and supporting operations and is suitable for mining short and extremely thin coal seam with height of and width
·To alleviate hazardous and environmental problems caused by gangue accumulation and aquifer destruction gangue backfilling mining GBM technology is raised Zhang et al 2017b; Huang et al 2018 as shown in Fig 1 a When the gangues is transported from the surface to the underground filling equipment is used to backfill coal gangue into the
·JXSC as a service provider of mineral extraction since 1985 all the time focus on solving trouble during the ore mining process and supplying mineral processing solutions and equipment for various of metals including chrome silver gold titanium zinc tin lead and so on As for chrome mining we have built close relationships with many
·Shuang Wang a School of Mechanical Engineering Anhui University of Science and Technology Huainan China;b State Key Laboratory of Mining Response and Disaster Prevention and Control in Deep Coal Mines Anhui University of Science and Technology Huainan China;c Mining Intelligent Technology and Equipment Provinces and Ministries
·The amount of coal gangue a by product of coal mining and washing is rapidly increasing with the growing trend of energy consumption In addition for the reason of dust generated by the combustion of coal gangue the equipment is damaged and the combustion reaction is blocked hindering the use of coal gangue as an energy source
·Backfill mining is an effective way to control ground subsidence and govern gangue To solve the problem of thin coal seam mining under villages a new thin seam backfill mining technology was proposed This paper investigated a reasonable proportion of filling materials by experiments designed the filling system and introduced key technologies for thin
·According to the current situation of the shearer technical equipment for thin seam the corresponding strip filling technique on the selective mining of coal and gangue was put forward as well
Media Attributions; Metal deposits are mined in a variety of different ways depending on their depth shape size and grade Relatively large deposits that are quite close to surface and somewhat regular in shape are mined using open pit mine methods Figure in Section Creating a giant hole in the ground is generally cheaper than making an underground
·Due to the relatively mature filling system and equipment the gangue feeding system the storage system and four column and six column filling support with a tamping mechanism and the mining filling process single and double interlaced and coal mining tamping fully mechanized solid filling technology has become the main development
1 ·The large scale open air storage of coal gangue often leads to oxidation and decomposition due to natural weathering resulting in decreased strength and instability which limits its wider application in concrete pavement To address these issues this paper proposed a composite consolidation treatment for weathered coal gangue WCG assessing its
