In engineering the drilling string flexure affect by kinetic energy and the potential energy. According to the energy method,it has 9tudied the relations drilling string biggest rotational speed with the critical axial force during the drilling string flexure,then it has established the drilling string and the axial critical force mathematical model. The research indicated that the drilling string loses the steady condition to conform the reality.it is advantageous to the screw coal miner important instruction significance to the design.
