Abstract
The condition in the coal mining section of Huaibei are very complicated. The strata pressure of the coal mining sections are affected by different factors. The paper studied the strata pressure behavior law of the fully mechanized coal mining face with soft roof, soft coal and soft floor in Huaibeij Coal Mining Area, which provided the science references to enhance the roof control of the fully mechanized coal mining face and ensure the safety coal mining operation.
