Determination of fracture initiation locations during cross-measure drilling for hydraulic fracturing of coal seams... Following these calculations, physical experiments were carried out to emulate cross-measure hydraulic fracturing under stress conditions equivalent to those in the Chongqing Tonghua coal mine, China....
Analysis on the initial cracking parameters of cross-measure hydraulic fracture in underground coal minesInitial cracking pressure and locations are important parameters in conducting cross-measure hydraulic fracturing to enhance coal seam permeability in underground coalmines, which are significantly influenced by in-situ stress and occurrence of coal seam....
Cross-measure directional drilling... The same technology has been utilised for cross-measure drilling in adjacent seams other than the working seam and also in surrounding strata....
