Dust pollution in open pit coal mines is one of the significant challenges to realize green mining. Therefore, research on dust ...
It is worth noting that obtaining long-term data on mine dust concentration poses challenges. In other studies on dust concentration in the open-pit coal mine, Ma et al. (2022) analyzed the distribution law of dust concentration and its influencing factors in the Anjialing open-pit coal mine through a multi-point network monitoring method.
Dust pollution from Chinese open-pit coal mines (OPCMs) threatens the coexistence of resource development and environmental protection. This research …
The Effects of Drilling and Blasting Operations in Open Pit Mines. Open-pit mining operations are integral to various industries, but they often grapple with the challenge of dust generation. Let's explore the impact of drilling and blasting in open-pit mines: Drilling Operations
In this blog post, we take a look at the sources of dust in open-pit mines as well as some of the most effective control measures mine operators should be implementing. Sources of dust in open-pit mines . Dust from haul roads is a particularly prominent concern for environmental and safety managers as well as pit managers.
Based on the dust concentration data and meteorological environment data monitored at the open-pit mine site, the characteristics of dust concentration and the influence of temperature, humidity ...
The particulate pollution in the open-pit coal mines of China is particularly severe in winter. The aim of this study is to understand the pollution characteristics of particulate matter (PM) in winter and provide …
Dust pollution from Chinese open-pit coal mines (OPCMs) threatens the coexistence of resource development and environmental protection. This research introduces a new approach to designing OPCMs based on meteorological indicators for dust removal and diffusion. It analyzes the production, distribution, and dust emission …
Microbial dust suppressant could adapt to the complex dust source conditions in open-pit coal mines, especially for dust with partial soil. Different …
To control the dust pollution caused by open-pit coal mining and reduce or avoid the secondary hazards of existing dust suppressants to the environment, a biological dust suppressant was prepared through the synergistic effect of a surfactant and an enzyme-induced carbonate precipitation. The optimal ratio of biological dust …
green and climate-smart mining in open-pit mines (Jiskani et al. 2021, 2022a; Tian et al. 2022, 2023). Notably, particu-lar attention has been given to addressing mine dust pollu-tion (Wang et al. 2021; Luo et al. 2021). Regarding dust pollution in OPCMs, dust prevention and control have con-sistently remained a focal point of research.
1. Introduction and background1.1. Mine dust pollution and its environmental & health risks. As the world's resources continue to be exploited, mining activities are giving rise to increasing environmental damage and pollution, of which mine dust pollution is considered to be one of the biggest threats to environment and public …
Most open pit coal mining operations have dust control plans that guide their operation teams on how much water should be used - but is this actually effective?. Although it's good to have an expectation of a difference between the dust control plan and the actual execution, it's important to have a good understanding of how effective the plan is and …
and theoretical reference for breaking through the bottleneck of dust prevention and control in winter, which most open-pit coal mines in China face in their efforts to progress into green mining. 2. Literature Review In terms of air pollution, it is reported that dust emission from surface mining is more than those from underground mining [21].
