- W2044218273 abstract "An experiment extracting CBM with surface borehole from mining subsidence area of a 6.25 meters thick coal-bed workface was done in Jincheng city. The test borehole was designed three stages based on the geologic structure of test field. During underground workface passed through borehole, the operational status of well was recorded and the deformation of casing was detected four times. Test has shown that the highest pure flow of surface borehole can reach 8m3/min which proves that the methane extraction technology with surface borehole from mining infection zone has a bright future for application in Jincheng city. But, how to maintain the stability of casing avoiding damage is still a problem, which should be resolved before the drawing technology is used in Jincheng extensively. Besides, the ordinary protecting skills for borehole used in oil exploitation cannot take a satisfactory effect to protect tube against damaging due to overburden rock movement during mining. The casing will be damaged at several positions, especially near the junction of soft and hard strata. It may be right measure to expend the diameter of tube or install special defensive joints at the places where will deform badly under the mining influence." @default.
