{"product_id":"near-surface-hydraulic-fracture-von-andrew-bunger","title":"Near-Surface Hydraulic Fracture","description":"\u003cp\u003eOn April 30, 1999 an estimated 10,300 square meters of roof area collapsed at the Moonee Colliery longwall coal mine near Sydney, Australia. The collapse itself was not the problem; longwall coal mines are nearly always designed such that stabilization occurs through frequent caving events in the mined-out region behind the longwall face.  The problem was that it occurred on a very large  scale and without warning. A miner was injured when  he was thrown by the resulting wind blast, and the  mine was shut down contingent on mitigation of the  hazard. The CSIRO Medal winning solution to this  problem was to use hydraulic fracturing, applied  for over 50 years for stimulating oil and gas  production, to induce controlled caving of the roof  rock. This development, as well as other new  applications for environmental remediation and  modelling the growth of magma-driven sills and laccoliths, motivated a new area of research aimed at understanding hydraulic fracture interaction with a nearby free surface. The work presented here comprises a detailed investigation into near-surface hydraulic fracture growth using analytical, numerical, and laboratory-scale experimental methods.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838319179\"\u003e\u003ch3\u003eLaboratory Experimentation and Modeling of Shallow Hydraulic Fracture Growth\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838319179","offer_id":39498937434205,"sku":"9783838319179","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/70b836a2-0d28-408a-b6a2-005300c9ceee.jpg?v=1770530212","url":"https:\/\/shop.autorenwelt.de\/products\/near-surface-hydraulic-fracture-von-andrew-bunger","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
