Method for predicting coke boulder yield

The invention discloses a method for predicting coke boulder yield. The coke boulder yield is predicted according to the following formula: coke boulder yield =-6 * Vdaf-4. 5 * Wn + 50 * Dt + 7.5 * Gn-48 * Kn + 4 * Yn + 0.8 * Tn + 37.5, wherein Vdaf is volatile matter%; wn is moisture%; dt is the tamping density, and the unit is g/cm < 3 >; gn is the number of interlayers, and the unit is layer; kn is the thickness of the coal seam, and the unit is m; yn is the thickness% of the gelatinous layer; tn is coking time, and the unit is hour. According to the method, the influence factors of the yield of the boulder yield of more than 80mm are analyzed and confirmed, the prediction model is fitted through a data statistics method, the accuracy is relatively high through actual production verification, technical support is provided for the coking plant of the heat recovery furnace type in the aspects of production method formulation and sales strategy planning, and the enterprise cost control and sales strategy plan
