As of this writing (ca 1994) none of the newer lead smelting technologies has been adopted in the United States. Also, no new lead mine has opened in the United States since the early 1980s. Most of the known U.S. reserves for lead are located in federally owned land in Missouri future mine development depends on the outcome of the U.S. government s intent to reform the Mining Law of 1872.

Estimation and prediction as to whether waste rock and tailings will produce acid mine drainage (AMD) are precursory to environmental certification, and therefore are a critical step in mine development. Kinetic tests are carried out using a cell or column that are operated over a period of typically 1 year, whereas static tests are a onetime measurement to determine the acid producing potential (AP) and...

The question I ask is "Can even this be done " I would answer that it is possible if everyone really wanted to. But first some long term compromise on non-health-related air pollution standards would be necessary. Few investors will risk capital for mine development when pollution requirements could make coal mines environmentally obsolete years before their normal payout period. 

Taking these facts into mind I decided to design, build and test a weapon that would be easy to make and highly effective. Ater toying with the idea and encountering a few fall-r AO friend of mine developed the...

Suggest that the best azimuth of the axis of subsequent roadway workface is 16.3° on NNE according to the distribution characteristics of in-situ stress and the situation of mine development, improve the scientific and reliability of ground pressure control in the condition of complex structures. 

The core problem of aging mines is that the remaining resources are inadequate, which is a big bottleneck of restricting aging mines development. 

Aging mine developing low carbon economy is in line with the coal group company s overall development and the overall layout ... 

Aging mine developing low carbon economy for the national coal industry similar type of aging mine second development provides a good model and example, has a strong demonstration effect. 

Aging mine developing low carbon economy fits the requirement of the current low carbon economy development situation at home and abroad ... 

As for the productive mines, various mine environment geological problems have occurred or are occurring, but seriousness of these problems differ from it in closed mines. If these problems were solved only by prevention, they would definitely restrict exploitation and aggravate the conflict between mine environment protection and mine development. If these problems were not treated properly, it means chronic suicide and runs counter to the aim of sustainable development. 

How to treat these mine environment geological problems, on the promise of protecting mine environment and accelerating mine development, is an urgent task. Therefore, the graded classification, which is a useful attempt to meet the requirement of mine geology environment treatment, is put forward.
