“…Assuming the volume of air in the tyre did not change with pressure, and based upon the constructed geometric model of the tyre and rim, the volume of air in the tyre was determined to be 1.003 m 3 [29]. However, according to the data available from the tyre manufacturer, the tyre volume was 0.988 m 3 , but the manufacturer did not specify the influence of the shape of the wheel rims on the air volume.…”

Tyre replacement and inflation is a common occurrence in the transportation, construction and mining industries, but in commercial, off-highway, or earth-moving vehicles, the rupture of an inflated tyre can cause serious or even fatal injuries to an operator. This paper highlights the consequences of a burst tyre based on a real case. The presented analytical approach is based upon an assumed adiabatic process and continuum mechanics using Bernoulli’s flow equations. A numerical analysis of a tyre burst was performed using multibody and finite element methods to reconstruct the fatal accident. It was shown that tyre-blast injuries may lead to lethal head trauma and bodily injuries, since the potential energy stored in large, over-pressured tyres can exceed 1 MJ.

To accurately correct wind resistance acquisition problems during the ventilation reconstruction and then calculate the air quantity in various roadways, taking the reconstruction of ventilation system in Shaqu Coal Mine of China as an example, the "calculation-feedback-correction" mechanism for adjusting roadway wind resistance was proposed based on the Ventsim simulation technique. Wind resistance was calculated and the change of air supply-demand after the reconstruction of the ventilation system was analysed using the proposed mechanism. The reasonable isolation reconstruction program was verified. Finally, the relationship between opening area of air window and wind resistance after the isolation reconstruction was fitted by the Fluent technology and the optimal opening area of air window was calculated. Results show that: (1) the ventilator area of the south upcast inclined shaft 1# operates unstably after the isolation reconstruction; (2) when the opening area of air window reaches at least 3.28 m 2 , the ventilator works normally and steadily. The results also demonstrate that good ventilation effect can be achieved by adjusting resistance reduction and setting the optimal opening area of air window which conforms to the actual status of ventilation systems.

“…Numbers of pilot scale units utilizing ventilation air methane as a subsidiary fuel in units of fluidized bed combustion Small percentage of engine fuel using a small percentage of ventilation air are preferred, even though there is no complete oxidation of methane occurs in these fluidized bed [38]. During the combustion process fluidized beds suspend solid fuels on upward blowing jets of air because of this there is a turbulent mixing of solids and gas.…”
