Abstract

A method for stimulating production of resources from a coal seam includes forming a drainage well bore in the coal bed that has a first end coupled to a ground surface and a second end in the coal seam. The method further includes inserting a liner into the well bore.
The liner has a wall including a number of apertures and a second diameter that is smaller than the first diameter of the drainage well bore such that a gap is formed between the wall of the liner and the well bore. The method also includes collapsing the drainage well bore around the liner to relieve stress in the coal seam proximate to the liner.
