Regulations governing mining operations are specific to national and jurisdictional regulations and local circumstances. While their variation precludes an extensive review in this report, given that regulatory failures and inadequacies contribute to tailings dam failures (Golder and Associates 2016), an international regulatory systems review would be beneficial in improving tailings management.
Tailings Dam failures are a shared responsibility, caused as much by regulatory as management failure. In cases of catastrophic failures, the regulatory system has failed to ensure good design, and to implement, monitor and enforce adequate standards. As ICOLD determined, these failures are frequently human-caused. Regulatory systems with multiple, independent checks are required to ensure standards and detect impending failures.
A regulatory system, for example, should cover the civil works, environmental performance and risk calculations associated with tailings storage facilities. They should also stipulate financial requirements for perpetual management of waste or a requirement for rehabilitation to a level that enables the site to be safely relinquished for reuse for non-mining purposes. While the practical requirements for mine waste planning, treatment, storage, monitoring and management are highly specific to the mine location, some higher-level issues are widely applicable. The figure illustrates an evolution of tailings management, from proponent-driven to a gradual increase in regulations for a more inclusive approach that would reduce risk for all stakeholders.

THREE MEN, "STOPE B, 4TH LEVEL" MINING, CANYON COPPER CO. MINE ON HORSESHOE MESA. GRANDVIEW CIRCA 1907. .
Impressions of the dazzling topography of Grand Canyon have changed and shifted since that day in the summer of 1540 when Garcia Lopez de Cardenas gazed out from the South Rim. The conquistador saw a worthless desert wasteland, nothing more than a barrier to political expansion. At the opposite extreme, the modern view tends toward the romantic, reveling in what we today perceive as the remarkable spirituality of the gorge. Products of the age in which they lived, American pioneers arriving in the 1890s were more practical and utilitarian: they assumed with so much exposed bedrock inevitably there had to be mineral riches waiting to be claimed by those willing to go below and look. Would-be miners fanned out across the inner canyon, probing everywhere, and at a place called Horseshoe Mesa found what they sought. Rich copper deposits initially averaging 30% pure promised wealth, but only if transported from the depths. Optimism reigned supreme, a route was scratched out, and in February 1893 an endless succession of mule trains began moving raw ore to the rim along a rough canyon track originally known as the Berry Trail, more recently as the Grandview Trail. More than any other canyon trail, the Grandview is steeped in the legacy of the mining days at Grand Canyon. Numerous small artifacts associated with these halcyon days are scattered across the top of Horseshoe Mesa, providing a link across the years. Hikers can inspect the physical remains of this bygone era while enjoying canyon scenery
at its finest.

Mining in the Swansea Area began around 1862, but major activity had to wait for the coming of the railroad. In 1904 the Arizona & California Railroad began constructing a line from Wickenburg to Parker. Seeing an opportunity for further development several of the original miners, Newton Evans and Thomas Jefferson Carrigan, secured investment money and began to develop Swansea.
By the end of 1908, a 350 ton capacity furnace, a 3.5 mile water pipeline from the Bill Williams River, and the hoists for five mine shafts were under construction.
By 1909 Swansea had a population of 500. The following year the Arizona & Swansea railroad began operation from Bouse. The railroad was key in moving supplies and people in and out of the growing mining town. Financial problems set in by 1911 and the mines shutdown with a brief reopening in 1912.
The American Smelting and Refining Company bought the mines in 1914 and rebuilt much of the town. The new owners ran the mines until 1937 when the Great Depression closed the mines for good.
Virginia City is a census-designated place (CDP) that is the county seat of Storey County, Nevada. It is part of the Reno–Sparks Metropolitan Statistical Area. The population was 855 at the 2010 Census.
Virginia City is one of the oldest established communities in Nevada. Like many cities and towns in the state, Virginia City was a mining boomtown; it appeared virtually overnight as a result of the Comstock Lode silver strike of 1859.
At its peak, Virginia City had a population of over 15,000 residents and was called the richest city in America. During the 20 years following the Comstock success "about $400 million was taken out of the ground." Most of the miners who came to the city were Cornish or Irish. In 1870, Asians were 7.6% of the population. When the Comstock Lode ran out in 1898, the city's population declined sharply.
Virginia City could be considered the "birthplace" of Mark Twain, as it was here in February 1863 that writer Samuel Clemens, then a reporter on the local Territorial Enterprise newspaper, first used his famous pen name.
Many locals work at the shops in town that cater to tourists, while others seek jobs in the surrounding cities. Virginia City draws over 2 million visitors per year and is listed on the National Register of Historic Places.

So the story goes from the guy with all these hidden treasures is that this is a stamping mill and according to him he had a partner at one time and the orginal mill deteriorated then with some help they rebuilt it. That's what he said anyway. Then something about a mine hole they had covered up whenthis old guy came up seen what they did and had a total fit. That's the way the story went.

In the graveyard of St Mary's Seaham. Contains the body of Thomas Hutchinson aged 25, killed in the Seaham Colliery Explosion of 1871 in which 26 men and boys died and in which his father was badly injured. Contains body of the father, Thomas Hutchinson, aged 60, killed in the Seaham Colliery explosion of 1880 in which 164 men and boys died. The relevant inscription now is partly obscured due to weathering.

I built this quite sometime ago, it was shortly after the first Power Miners sets were released whenever that was.
Anyway those sets inspired me to make this. I have never really built a wheeled vehicle before and I think its decent for a first try, though I will admit the blade on the front looks tacked on.
And a little tid bit you might like to know is the upper chassis is seperate from the axle/wheel assembly.

GHH mining machine underground shovel, when they were introduced in the Monteponi mine, helped to make the work lighter and faster. He wouldn't mind seeing it displayed in a protected area and not exposed to the elements. A machine created to work indoors that ends its "career" outdoors. The most interesting part are the reinforcements made by hand welding along the entire profile of the blade of the shovel. Although not a certainly functional artistic work; this is proof of the mastery and skills that the staff had acquired in working in a mine like this.
Pala da sottosuolo GHH mining machine, quando vennero introdotte nella miniera di Monteponi aiutarono a rendere il lavoro più leggero e veloce. Non sabbe male vederla esposta in una zona protetta e non esposta alle intemperie. Una macchina che nasce per lavorare al chiuso che finisce al sua "carriera" all'aria aperta. La parte più interessante sono i rinforzi realizzati con saldatura a mano lungo tutto il profilo della lama della pala. Seppure non un lavoro artistico sicuramente funzionale; questo a riprova della maestria e delle competenze che il personale aveva acquisito nel lavorare in una miniera come questa.
Early in the history of the mine all of the work was done by hand. The coal was drilled with a hand auger and blasted free. Then scooped up and loaded into a horse-drawn cart to be hauled out. The roof was supported by timbers and posts. If the caged canary stopped singing and died, it gave warning to the miner that the air has started to go bad or that potentially explosive methane was building up.
