Drilling blasting is the main construction method of roadway mining. In the process of designing the drilling parameters of rock roadway, the design of the cutting technology parameters is very important. Through the analysis of shaped structure mechanics of crack extension theory, combined with the operation condition of the coal rock roadway blasting construction, the multidirectional shaped cutting device, the preliminary cut blasting method and parameters were settled, the calculation and analysis for the demonstration was given, providing effective pre-blasting in roadway mining.
