In fact, you need a special kind of heavy geological hammer. See pic 1 - …
The hardrock mining industry is the single largest source of toxic waste and one of the most destructive industries in the country.
Hardrock minerals, such as gold, silver, and copper, play an important role in the U.S. economy by contributing to multiple industries, including transportation and defense. However, mining disturbs the land and creates the potential for serious public health, safety, and environmental hazards, particularly if a mine has been abandoned.

Hard Rock 101: Small-Scale Blasting. August 2020 by John Norman …the process remains much the same: Drill holes, load explosives, close up the holes, blast and muck out the resulting broken rock.
The Mining Bureau has separate programs for hard rock exploration and hard rock mining. Hard rock exploration requires a license to perform drilling and trenching and other activities to determine if an economical mineral resource is present. Hard rock mining can occur under a Small Miner Exclusion Statement (SMES) or under an Operating Permit.
However, the mining industry is often associated with negative environmental impacts, safety hazards, and social issues. As society becomes more conscious of the need for sustainable practices and responsible resource extraction, the mining sector transforms safe and sustainable practices.

Senator Romney joined Senators Heinrich (D-NM) and Risch (R-ID) as a cosponsor of the bipartisan Good Samaritan Remediation of Abandoned Hardrock Mines Act, bipartisan legislation that would make it easier for "Good Samaritans," such as state agencies, local governments, nonprofits, and other groups, to clean up and improve …
The web-based tour explores the history of the county's hard rock mining through historical and present-day photos, videos, oral histories and an interactive map that includes mining and milling sites, and the Switzerland Trail Railroad line. This virtual tour is meant to be an introduction to hard rock mining in the county.
In this guide, we shall discuss the methods used in mining hard substances. However, remember that underground (UG) mining of various types of rock requires …
Lithium is poised for a comeback in 2019. Trends in lithium mining are shifting, and hard-rock spodumene mining is getting more popular.
Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals such as those containing metals like gold, copper, zinc, nickel and lead or gems such as diamonds.
A recent analysis of AMC smart data reveals trends in Australian hard rock underground mining. Director of AMC Consultants Andrew Hall explains what the data reveals about the role of new technologies, including digitisation and automation, as well as the value of existing equipment.

This book presents the principles and practices of rock blasting for underground hard rock mining. It covers a theoretical background of the rock blasting technology and comprehensive case studies on different stages of rock blasting for underground metalliferous mining.
Hardrock mining on trust and restricted fee lands (tribal lands) is managed by governance structures at the tribal and federal government levels, in accordance with the approaches established in tribal and federal law. Tribes decide whether to allow hardrock mining on their lands.

Picture a hard rock mine where we safely and efficiently extract the targeted ore without the need for explosive blasting, our people safely out of harm's way.
But let's get into specifics. What exactly is it about this machine that allows it to replace machines like a Jumbo? At a core level, the MC51 approaches removing hard rock in a fundamentally different way than traditional mining methods or even tunnel boring machines. Where as both of …
Until the 1970s, mine operators could mine for valuable hardrock minerals—i.e., gold or copper—then abandon the land. On lands they oversee, federal agencies identified about 140,000 remnants of these hardrock mines, including unsecured tunnels and toxic waste piles.

is calling the MC51—a machine more than 10 years in the making—a continuous mining machine, and it's been designed to completely disrupt the traditional hard rock underground mining ...
Picture a hard rock mine where we safely and efficiently extract the targeted ore without the need for explosive blasting, our people safely out of harm's way. As precious resources become ever more difficult to access at depth, we are exploring technologies such as automation and even robotics to transform hard rock mining.
For hard-rock mining, there are two basic techniques that miners use. This includes the "room and pillar" approach for mining flat ore deposits and the "cut and fill" …
Hard rock underground mining has been wedded to the drill-blast method of breaking rock. Current practice and technology have focused on greater efficiencies in the blasting and handling of ore, on the basis that the lower costs that come with larger scale operations compensate for the waste dilution associated with the bulk methods.
