Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal,
Environmental hazards are present during every step of the openpit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose
Environmentally, potential negative effects of mining can include air, land/soil and water pollution of different kinds. Mining produces potentially
hard negative mining就是多找一些hard negative加入负样本集，进行训练，这样会比easy negative组成的负样本集效果更好。. hard negative mining思路在目标
Mining Contributes To Global Warming. Natural resources extracted through mining contribute heavily to global warming. Coal and oil are burned to power cars and our electric grid, releasing dangerous CO2 into the
Advantages of Mining. Mining can help us to assure the supply of important resources. Important for our technological progress. Mining is necessary for many products of our
什么是hard negative mining. 最近一直在看关于CNN的目标检测和跟踪的文章，在这中间会经常看到hard negative mining这个名词，把这个大概解释一下：. 假设
那么负样本中哪些是困难负样本 (hard negative)呢？. 困难负样本是指哪些容易被网络预测为正样本的proposal，即假阳性 (false positive)，如roi里有二分之一个目
Tailings, as they’re known in the industry, can contain toxic metals such as arsenic and mercury. In January , a tailings dam at an ironore mine in Brazil collapsed, killing at least 248
Background Mining activities, including prospecting, exploration, construction, operation, maintenance, expansion, abandonment, decommissioning and repurposing of a mine can impact social and environmental systems in a range of positive and negative, and direct and indirect ways. Mining can yield a range of benefits to
Environmental hazards are present during every step of the openpit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose
While Europe races on lithium fuel to reach net zero, it doesn’t seem to be aware of the damage it leaves behind. Lithium mining leaves a significant ecological footprint on soil, water, and air. Also, it leads to increased carbon emissions, the very thing the EU is trying to eradicate. Typically, lithium mining requires consuming large

Most mining operations degrade environment. Dust, water pollution, air pollution, soil degradation, noise, etc. are examples. This pollution stays there for a long time. There are some old mining operations in Rockies (in the USA) causing water pollution even after their retirement. If one person works as a mining employee for 5 years and he
Hard negative mining. The problem of finding relevant candidates for ranking losses (especially for triplet loss) has received a lot of attention in the recent years for both retrieval [2], [7], [19], [24], [25], [26] and tracking [27]. One research line bypasses this problem by proposing modifications of softmax loss for easier training [28
The impacts that are considered as positive like employment and development projects of the community, which are considered as important but the potential negatives cannot be setoff by them (Goudie, ).The negative effects of mining Industry on the environment are water pollution, biodiversity loss, air pollution, and erosion of soil
In the past 40 years, largescale, openpit mining has come to dominate the region — a technique that involves stripping away layers of rock to get at coal deposits deeper in the earth. A deformed cutthroat trout with its gill cover missing, found in the Elk River downstream of several major coal mines.
Competitive sliding window detectors require vast training sets. Since a pool of natural images provides a nearly endless supply of negative samples, in the form of patches at different scales and locations, training with all the available data is considered impractical. A staple of current approaches is hard negative mining, a method of selecting relevant

However, reclamation has been a viable way of reducing the negative impacts of abandoned mine lands and ensure productive and efficient utilization of mine wastelands. Compaction, low or high pH, low water holding capacity, gullies, bulk density, deficiency of micro, and macronutrients are the major factors limiting the productivity of
Advantages of Mining. Mining can help us to assure the supply of important resources. Important for our technological progress. Mining is necessary for many products of our daily life. Employment opportunities for many poor people on our planet. Can help poor regions to develop and to progress.
1. Erosion. One of the effects of mining on the environment is erosion. The enormous Ok Tedi Mine in Papua New Guinea is a perfect example of how nearby areas can be significantly impacted by the
A new report finds gold mining in Suriname increased by 893 percent between 2000 and 2014.

Gold mining is one of the most destructive industries in the world. It can displace communities, contaminate drinking water, hurt workers, and destroy pristine environments. It pollutes water and land with mercury and
