To master theoretical calculation for dust removal efficiency of high pressure atomization in an underground coal mine, the corresponding characteristics and were both comprehensively studied theory by virtue related theories hydromechanics aerosol. According to actual measurements flow coefficients angles X-type swirl nozzle, computational formula was derived atomized particle sizes such a nozzle conjunction with relevant empirical equation. Moreover, mathematical model applying mine also...

This study addresses inefficiencies in manual apple harvesting and high damage rates mechanical methods by developing an airflow-cushioned conveyor to minimize postharvest losses. Analyzing dynamics pipelines collision mechanics identified three key factors: fruit size, linear velocity, airflow speed. A Box–Behnken-designed response surface model linked these parameters area force. The results showed optimal settings for small (grade III: 11 m/min, 18.2 m/s; 34.24 mm2, 8.7 N), medium II:...

Abstract Pressure nozzle is commonly used in the dust-reduction techniques by spraying of underground coal mines. Based on internal structure, pressure can be divided into following types: spiral channel nozzle, tangential flow-guided and X-swirl nozzle. In order to provide better guidance selection nozzles for mine systems spraying, we designed comparing experiments study atomization characteristics performance four with different structures. From experimental results characteristics, both...

Most dust suppressants used for buildings currently lack sufficient resistance to harsh conditions, such as high temperatures and wind erosion. To solve this problem, it is necessary develop a new type of suppressant. In study, the guar gum molecule was chemically modified remove active hydroxyl group in order significantly improve stability adhesion gum. Eventually, composite suppressant synthesized by incorporating surfactant an absorbent agent into The functional groups reaction products...

This study proposes a ventilation and dust control approach using double-forced air pipes at the tunnel excavation face, aiming to optimize reduction measures for underground coal mining environment. We designed physical model in proportion 11,139 face Zhangji Coal Mine of China Huaihe Energy Holding Group Company. To begin with, CFD numerical simulation was employed unveil basic laws pipe approach, including airflow characteristics concentrations. The orthogonal experimental method then...

Abstract Rescues from building collapse accidents present a significant challenge for China’s emergency rescue system. However, there are also many risk factors in training scenario, which have been summarized this study. A hierarchical indicator system personnel safety was established, including 12 first-level indicators and 23s-level indicators. Then, an improved Grey-DEMATEL-ISM-MICMAC evaluation model constructed to evaluate the level of risk. Influencing factor scores were determined...
