直孔掏槽一次成井的改进TOPSIS-CV掏槽方式评价模型
Improved TOPSIS-CV method of cut blasting mode evaluation in one-step raise excavation with burn cut
摘要
Abstract
In order to optimize cylinder cut blasting mode for one-step raise excavation, an improved TOPSIS comprehensive evaluation model combining vertical projection approach was developed. Seven indexes considering the economy, technology and security were used, and the index weights were determined by coefficient of variance method to avoid the subjectivity. The improved evaluation model was applied to goaf dealing in a mine. Finally, the optimal scheme was applied in an industrial test. The results show that the best vertical distances between the scheme and positive of the four cutting modes were calculated and were 0.125 94, 0.089 89, 0.060 40 and 0.041 53 respectively, which indicate that the fourth scheme is optimal. Compared with the traditional TOPSIS, the improved TOPSIS tends to reveal clearer differences between schemes, which is convenient to optimize the scheme. The formed raise by optimal scheme is through up and down completely, and reaches the expected size.关键词
