	1	Assessing risks from mining-induced ground movements near gas wells显示文摘The proliferation of unconventional gas well development in the Northern Appalachian coalfields has raised a number of mine safety concerns.Unconventional wells,which extract gas from deep shale formations,are characterized by gas volumes and pressures that are significantly higher than those observed at many conventional wells.The gas is composed largely of methane as well as other hydrocarbons.Hundreds of planned and actively producing wells penetrate protective coal pillars or barriers within active mine boundaries,including chain pillars located between longwall panels.Gas released from a well damaged by mining-induced ground movements could pose a risk to miners by flowing into the mine atmosphere.The mining-induced ground movements that may cause well damage include conventional subsidence,non-conventional subsidence(e.g.bedding plane slip),pillar failure,and floor instability.This paper describes the known risk factors for each of the four failure mechanisms.It includes a framework that can guide the risk assessment process when mining takes place near gas or oil wells.
