Development of new compositions for dust control in the mining and mineral transportation industry
Записки Горного института, 2021 Dust control in summer and winter periods is a topical problem associated with conducting open pit mining operations; however, at negative temperatures the additional requirements are imposed on dust suppressants. Preventive compositions are proposed, in

Evaluation index of wind resistance performance of dust suppressant and its application
矿业科学学报This study proposes three evaluation indexes for evaluating the wind resistance of mine dust inhibitors, namely average loss rate per unit mass (ALRPUM) of dust suppressant, average suppression rate per unit mass (ASRPUM) of dust suppressant, and ...

Phytotherapy Research, EarlyView.ABSTRACT Asthma affects 260–300 million people worldwide. About 20%–35% of patients use medicinal plants with their asthma medication, often without telling their clinicians. Disclosure rates are low; up to 42% of asthma outpatients use herbal products, with no records in their charts.
