Abstract: The Shaqu Coal Mine is a typical compound roof mine. Its engineering geological conditions are affected by the multistrip structural zones. The roof and floor of the working face are composed of instability soft rocks. There is little water in the fractures. This paper investigates the characteristics of the insitu stress and ground overburden pressure. The Insitu stress testing of six sites were carried out in some main roadways. The test results indicate that insitu stress field is relatively uniform and belongs to the quasihydrostatic stress. The stress trepanning rescission and the surrounding pressure ratio measuring are applied. The tests find that the maximum principal stress value is between 2011 and 287 MPa. The coefficient of the horizontal pressure value is between n 225 and 285. The results show the site is of high stress. Local monitoring works of coal pillar bearing pressure are performed for the large and high fullymechanized mining roadway of the No. 24101 working face. Distribution of coal pillar bearing pressure of stope can be divided into a plastic failure region,a peak stress region and an in situ stress region. At the same time,the roof separation and bolt dynamometer load are monitored for the No. 14201 work face of the south side mine. The monitoring reveals that the main reason of weakened roadway stabilization is the accretion of roof separation with time increasing. These synthetic monitoring results can provide more practical value and basic data for design of the supporting and safety during the mine production.
