| Abstract: | In order to solve the objective problems that gasses pressure measurement of vertical drillhole is very difficult in deep well Caijiagang eoalmine, a new type of seal process of drillhole was proposed, namely seal of drillhole of high pressure- compound injection pulp- group obstruct. Through the industrial laboratory of No. 4 geology detection vertical drillhole, gasses pres- sure of coal seam B1 lb in depth of one kilometer was obtained successfully. Accordingly, the measurement result can provide technical support and references for the establishment of comprehensive improvement measure of gasses. |
