Due to the special properties of ammonium salts, acetate and citrate were used explore best leaching conditions rare earth with compound carboxylate. This paper explored influence molar ratio, concentration, experimental temperature, pH agents on efficiency aluminum, it analyzed process based kinetics, which provides a new method for from weathered crust elution-deposited ore. The results showed that under where ratio was 7:3 concentration 0.15 mol/L, highest when agent 4.0 temperature 313...
Ever increasing mine production capacity and mechanized operations enable advanced drilling equipment to be widely adopted in underground mines. In order achieve satisfactory blasting performance tunnel advance, there is a critical need optimize the technique match large deep‐hole capability. this study, through theoretical analysis of blasting, layout cutting holes was found key factor controlling performance. The effect first investigated by analyzing influence free surface hollow hole...
The seepage characteristics of sand affect its strength, mechanical deformation characteristics, and find safety stability. drag coefficient is a dimensionless physical quantity expressing the interaction between fluid particles, it also an important parameter that characterizes permeability granular soils. Through test standard with single particle sizes different grades, analyze laws in Darcy non‐Darcy seepage. relationship parameters b equation porosity ( n ), average size d 50...
The particle size distribution of tailing sand will affect its strength, deformation and mechanical properties, thus affecting the overall safety stability dam. main purpose this study is to obtain gradation samples with best shear strength seepage effect by studying influence on properties saturated iron sand. tailings were sampled from Yangjiawan reservoir Chengchao Iron Mine, moisture content test, analysis scanning electron microscope test (SEM) carried out samples. It measured that...
Owing to the lower visibility of water and flow velocity, tides, depths, terrain others, drilling blasting underwater are rather difficult. Combining with an actual rock reef project, using Causal Analysis Graph analyze potential hazards which can lead accidents on course underwater, combining Analytical Hierarchy Process, taking each hierarchy important degree, then Fuzzy Mathematics assess comprehensively safety construction underwater. Though results appraisals, method combing is feasible...
Tailings sand is the dam‐building material of tailings dam accumulation sub‐dam, and its mechanical properties directly affect safety stability whole dam. With improvement mineral sorting technology, content fine ultrafine particles in gradually increases, which will strength sub‐dam. To improve settling effect Chengchao iron ore mine (China), flocculation law on was studied. Polymerized sulfate (PFS) as an inorganic polymer flocculant, compared with traditional has a stronger adsorption...
<title>Abstract</title> Rock burst tendency evaluation is the basis of rock risk assessment in underground engineering. In order to realize accurate western Hubei, four parameters strength, uniaxial compressive strength σc, ratio tensile σc/σt, mass integrity coefficient Kv, tangential stress σθ/σc were selected as index Hubei.In measurement above indexes, location and phenomenon Hubei are summarized, sampled. Then, through combination field indoor tests, completed. Finally, based on Matlab...
The optimization of a mining sequence not only reduces stress concentration in surrounding rock but also prevents underground debris flows, significantly improving safety. Firstly, the 870–898 m level eastern area Tiaoshuihe phosphate mine was divided into 25 ore blocks, and six different sequences were designed for this area. Then, it calculated that five blocks must be processed simultaneously to reach annual production output. distances between mined will inevitably affect efficiency...
This study is aimed at numerically investigating the cnoidal wave-induced dynamics characteristics and liquefaction process in a loosely deposited seabed floor shallow water environment. To achieve this goal, integrated model FSSI-CAS 2D taken as computational platform, advanced soil Pastor–Zienkiewicz Mark III utilized to describe complicated mechanical behavior of loose soil. The results show that significant lateral spreading vertical subsidence could be observed due gradual loss skeleton...
