Abstract: In order to prevent the strong underground pressure of 42107 mining face of Buertai coal mine, the VB.net programming technology was used to analysis the monitoring data of resistance of hydraulic support in working face are used to extract the maximum value of mining cycle, and the cloud visualization analysis of which is carried out. The results show that the strong underground pressure of 42107 working face in Buertai Coal Mine is mainly affected by the hard strata between layers of 22 and 42 coal seams. Under the restraint of wide coal pillar, the area of hanging roof at the edge of goaf is large, and the roof activity at the head and tail of working face is inadequate; under the hanging roof at the edge of goaf, the underground pressure of advanced roadway in working face is strong; Because of the longer mining face, and the pillar of the upper 22 coal seam, there is strong ground pressure in the middle part of the working face. Based on the law and mechanism of strong underground pressure, the prevention and control method of strong underground pressure is discussed. The practice shows that the control effect of strong underground pressure is good.
