Answer 1

Can't find anything on "Shay oil mining" but this is shale oil mining which is most common:

Environmental considerations

Main article: Environmental impact of oil shale industry

The oil shale industry can have a negative impact on the surrounding environments, if the risks associated with it are not managed correctly. Environmental concerns raised over the extraction of shale oil have caused the oil shale industry in some countries to come to a halt.[45][46] In 2004, opposition to the proposed Stuart Oil Shale Project in Australia resulted in it being put on hold.[46][47][48] A United States law prohibits United States government agencies from buying oil produced by processes that produce more greenhouse gas emissions than would traditional petroleum including oil shale.[49]

Surface-mining of oil shale deposits have the same environmental impacts as those of open-pit mining. In addition, combustion and thermal processing generate waste material, and the atmospheric emissions from the process include gases such as carbon dioxide, which is a major greenhouse gas. Experimental in-situ conversion processes and carbon capture and storage technologies may reduce some of these concerns in the future, but at the same time they may cause other problems, which include groundwater pollution.[50]
