By means of numerical simulation, theoretical analysis and field practice, bolt-grouting supporting technology of heavily stressed weak-rock roadway in deep ground is studied wholly and systematically.

With the decreasing of the coal resources in shallow bed,coal mining will shift to be in deep one after the other,and at the same time the research on the surround-rock\'s deformation-failure mechanism in deep-mining high stress roadway is becoming more and more important.

According to the features of the superdeep and extra-high temperature reservoirs in the Donghetang Oilfield, Tarim Basin, RMT (reservoir monitoring tool) is preferentially used for logging operations in this oilfield.
