Stress Relief and Stimulation of Coal Reservoir by Hydraulic Slotting

چکیده
Coal seam permeability is one of the key factors influencing gas extraction efficiency, which great significance to reduce coal and dynamic disasters in gassy mines. Hydraulic slotting technique an effective method stimulate reservoir, but selection parameters has impact on efficiency. For this reason, hydraulic model was established by using FLAC3D software analyze stress distribution before after slotting. Then, influence borehole diameter, width, length relief also discussed. The results show that width a seam, while diameter have no obvious that. Based numerical simulation, field tests were carried out Sangshuping NO.2 mine. can be fully released, resulting improvement permeability. efficiency highly enhanced This research achievement provides guidance basis for high-stress water jet technology with adaptive different geological conditions.

Easy Stress Relief by EZH2
While we are beginning to appreciate the cellular roles played by long noncoding RNAs, the function of transcripts emerging from repetitive genomic regions remains enigmatic. In this issue, Zovoilis et al. report that the polycomb protein EZH2, upon heat shock, facilitates transcription of stress-responsive genes by inducing the degradation of the transcriptional repressor B2 repeat RNA.
متن کاملDynamic Behaviour of Hydraulic Pressure Relief Valve
This paper discusses the influence of the radial clearance of the poppet of the direct spring operated pressure relief valve type DPRS06K315 on the dynamic behaviour of the valve. The mathematical model of the valve has been developed; these mathematical terms have been represented in Matlab/SIMULINK. The results obtained by a simulation describe dynamic behaviour of the valve and its influence...
