大倾角煤层工作面矿山压力规律研究

he steep seam mining face of the pressure measured in the study of steep seam down pseudo-ramp sub-pillar mining method and the straight-line method of longwall coal mine tunnel and face pressure behavior pattern of on-site observation and laboratory test The study, based on a comparison of two coal mining law the law of pressure behavior, analysis of the pseudo-down ramp sub-pillar mining method can greatly ease the pressure behavior mine uneven phenomenon mechanism, to explore the use of this type of mining law , Face-support sub-set of reasonable parameters for the design and optimization of mining face pressure to provide a scientific basis for control, to ascertain the face of pressure behavior law of mine, on the one hand, select the face of reliable and reasonable The way of supporting and strengthening the management of the roof of the scientific research and design. On the other hand, to strengthen the management of the tailings as well as static safe production of the corresponding construction planning.
