According to the work environment of shearer in steeply inclined fully mechanized mining face, the program of shearer slope design is designed to simulate the working status of shearer when working face with steeply inclined fully mechanized coal mining face. Through the introduction of the climbing test program and the calculation and analysis of the selection of shearer climbing and braking capacity, the shearer can complete the 35 ° climbing test. In the experiment, the improvement of the shearer’s braking system can ensure the reliability of the shearer’s braking system. The test can be used to test the performance of shearer’s climbing performance, braking effect and hydraulic system, and to study the stress and working conditions of shearer in large inclined face, which can shorten the research and development cycle of large shearer with high power, Improve product reliability.
