What you don't understand is that mined areas are typically marked off, which is why it's children who are most often affected because they're more likely to ignore warning signs. Nonetheless because most people stay away from those areas the risk is lower. When you demine an area, you signal that it's safe for the population to move in, which means that if you haven't actually cleared 99% of the mines you're increasing the possibility of a person stepping on a mine. That's the reason the UN demands such a high clearance rate before an area can be declared safe for humans to live in.
