Question

how do people die in mines ? do they not take safety measures

Answer 1

A mining accident is an accident  that occurs during the process of mining minerals. Thousands of miners die from mining accidents each year, especially from underground coal mining, although hard rock mining is not immune from accidents. Coal mining is considered much more hazardous than hard rock mining due to flat-lying rock strata, generally incompetent rock, the presence of methane gas, and coal dust. Most of the deaths these days occur in developing countries, and rural parts of developed countries.

Mining accidents can have a variety of causes, including leaks of poisonous gasses such as hydrogen sulphide or explosive natural gases, especially firedamps or CH4,dust explosions, collapsing of mine roofs mining- induced seismicity, flooding, or general mechanical errors from improperly used or malfunctioning mining equipment.Use of improper explosives underground can also cause methane and coal dust explosion
