Q

Describe the difficulties of mining.

A
  • High mountains with steep cliffs rising to 1200 metres and even higher!
  • When you find them, it is hard to tell what their quality is.
  • Mining is very hard work high in the mountains, where everything has to be carried by horses or donkeys, or by the miners themselves.
  • Some gemstone mines can only be reached by climbing ropes up the cliffs.
  • Getting your equpment up is difficult.
  • The ground is usually frozen with few months of suitable weather from June or July to September or October.
17
Q

Who runs most gemstone mining in remote places?

A

Most gemstone mining in remote places is run by small groups of miners using very simple methods.

18
Q

Why have Large mining companies not developed the mines in high places?

A

Large mining companies have not developed the mines in high places because it is too difficult to get modern mining equipment up there. Some modem equipment would not work up there because of the low air pressure.

19
Q

What do miners use to mine?

A

The miners use simple equipment: hammers and chisels, gas or gas-powered drills, and sometimes Illegal explosives, which can damage the gemstones.

20
Q

Describe the problem of air pollution while mining.

A

The air in the mines soon becomes too polluted with gas and dust: when it becomes too bad, the miners have to stop work. They wait until the air has cleared naturally overnight, and then they continue.

21
Q

Describe the dangers the miners face.

A

These miners have no modern safety equipment such as breathing equipment, air filters, or ventilation-not even face masks. Nearly all miners have lung problems and many suffer from carbon monoxide poisoning. But, the main causes of death and ingury are falls from cliffs, being buried when mines collapse, and being hit by falling rocks.

22
Q

Do the miners who survive become rich?

A

There are reports of some gemstone miners making a good living, but most of the precious stones are not property mined and are damaged. Most miners sell the gems in their raw fom-very cheaply.

23
Q

What projects are being started to teach miners? What are they about?

A

However, there are new projects to teach people in these mountain regions how to cut and polish gemstones and to set up proper trading centres where miners can sell their gems for better prices.
