2. higher risk of lung disease in surface mining
3. higher risk of mine collapse in surface mining
4. lower risk of hearing loss in surface mining

Option 2 is correct: The health impacts of surface mining are different from those of underground mining in terms of a higher risk of lung disease in surface mining. Surface mining involves the removal of the topsoil and exposing the rocks and minerals underneath. The process releases a large amount of dust and other pollutants into the air, which can be breathed in by workers and nearby residents. This increases the risk of respiratory and lung diseases such as silicosis, black lung, and asthma. In contrast, underground mining poses a higher risk of miner injuries, mine collapse, and hearing loss due to the use of heavy machinery and the proximity to the blasting and drilling sites.
