How can both surface and underground mining? select the two correct answers
a) risk of injuries from methane explosions
b) risk of high blood pressure
c) risk of injuries from mine collapse
d) risk of disease like silicosis
e) risk of injuries from heavy equipment

D) risk of disease like silicosis

E) risk of injuries from heavy equipment

Explanation:

For both surface and underground mining, miners can suffer from silicosis and they can get injured heavy earth moving machinery.

Silicosis is often tagged miners' disease. It results from the prolonged inhalation of quartz, silica,e.t.c through the lungs. Most mining activities display a large amount of dust which can lead to silicosis.

Mining uses heavy equipment to remove earth and access ore bodies within the rock. This is also a risk in underground and surface mining activities.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
