Answer:
Traditional mining techniques can have a severe impact on the environment, and some popular methods — like open pit and underground mining — present some of the most significant environmental risks. By instead using new, alternative low-impact mining techniques — like in-situ leaching — mining companies can reduce their environmental impact. With many of these techniques, companies can significantly reduce surface disturbance at mining sites, lower soil erosion and move less material that would need backfilled. Lowering interference in this way can both reduce environmental impact and result in less work when preparing a site for quicker revegetation or rehabilitation.

Block cave mining is a better mining alternative to Open-cast mining.
surface mining is fine desirable to extract minerals that are near the surface of the earth. it is also typically an extra cost-effective mining approach in comparison to underground mining. not unusual minerals extracted using floor mining are a number of the maximum mined consisting of coal, iron and bauxite.
Block cave mining is the most effective underground technique that may offer comparable open pit production quotes and operating prices. for brand new traits, block cave mining gives the in addition gain of a smaller surface footprint with notably much less waste disposal necessitie.
