Low-grade and high-reserve scheelite, which is associated with calcite, has similar surface properties that cause difficulty in separation. In this study, sulfomethylated kraft lignin (SMKL) was used as a novel eco-friendly inhibitor for the flotation separation of scheelite calcite. The test results showed 60 mg/L SMKL had significant influence on depressing calcite flotation, while it slight effect flotation. Furthermore, enhanced WO3 grade concentrate artificial mixed ore to 62.02%...
The sensitivity analysis is an important method to realize the intelligent control of branch air volume for mine ventilation network. Aiming at current situation that on-demand (VOD) regulation cannot meet large demand in specific consumption branches mine, this paper proposed a multi-branch wind resistance joint based on Based theory, concept change rate was quantitatively analyze law resistance, and calculation formula matrix obtained. Lagrangian interpolation used further optimize...
Summary In coal mining, smoke flow from tunnel fires can easily cause a large number of deaths in the ventilation network. But optimal path control methods and automatic system were lacked. order to improve efficiency fire emergency rescue, mechanism regional linkage for induced network was studied. Based on mines, different scenarios analysed using simulation software (VSS). Smoke simulated under modes, contrastive analysis conducted respective effects confirmed scenarios. A new type...
Ventilation facilities could easily be destroyed by gas explosion in a coal mine and usually lead to the cascade collapse of entire ventilation system. Altering increase value overpressure peak propagation speed shock waves. The attenuation law for blast waves restricted roadway networks was analysed, calculation models wave smoke flow velocity tunnelling roadways were derived. An relief air door with magnetic lock then designed. This is opened action relieve pressure large section....
Considering that once a fire breaks out in the cross transfer subway station, it will cause heavy casualties. The best smoke exhaust mode is developed to toxic gases, assist passenger evacuation and firefighting. FDS Pathfinder models were constructed for selected stations verify advantages disadvantages of each under different locations heat release rate scenarios. Ten bottlenecks identified, critical hazard index at scenario was statistically analyzed calculate available safe egress time...
