Why might surface mining be less risky for miners than underground mining? a. surface miners can become trapped in a collapsed mine. b. surface miners work in dusty, enclosed areas. c. surface miners work aboveground. d. surface miners use elevators to enter mines.

Destruction of land, mine explosions, collapses and flooding surface subsidence,surface heaps

Explanation:

Surface mining might be  less risky for miners than underground mining because of the following

1. Underground mining is more expensive than surface mining.It takes more time and energy to mine for coal in the underground

2. Destruction of land surfaces: Underground mining actually leads to the damage to landscape. The lands change form and topography due to the mining activities.

3. Surface subsidence,

4.Abandoned shafts and extensive surface spoil heaps,

5.Explosions: There is what is known as the triangle of fire. For a fire outbreak, there must be oxydant. fuel and ignition. Once these three are in place, an explosion can occur which can lead to loss of lives and equipments etc.

6. Collapses:  Landslides might occur

due to tampering with the earth's layer during underground mining activities

7. Flooding: During underground mining, The table water can be be disrupted which might lead to flooding
