摘要：

Groundwater impacts are a common reason for opposition to longwall mining. Most impacts are due to subsidence-related fracturing. Although upper aquifers are protected from drainage to the mine by a confining zone, water levels decline due to fracture dilation, and drawdown expands outward a few hundred meters. Recovery of water levels is common.
