Abstract: By comparing the test data from test drilling of Dingji coal mine,on the basis of clearing reaming and fracturing antireflection mechanism of three dimensional rotational water jetting,the paper summarzes and analyzes the process parameters which influence the reaming and fracturing antireflection of three-dimensional rotational water jetting,and determines the range of process parameters by using the means of theoretical analysis combing with the practical.The results show that the process parameters can be divided into process parameters and drilling construction parameters.According to the actual situation of Dingji coal mine,the process parameters are determined as controlling the reaming pressure at 10～15 MPa;the inner diameter of pipeline should be greater than 25 mm;fracturing pressure is determined in 18～20 MPa;the space between test drilling and control drilling is 10 m.
