模糊数学在改进掘进支护参数中的应用

合理的掘进参数的确定对于建设高效高产现代化矿井具有重要意义,而应用模糊数学综合评判法可以全面而客观的评价出影响巷道掘进的主要因素.本文在现场调研的基础上,通过应用模糊数学综合评判法,找出了影响巷道掘进支护的主要因素是金属支架构造不合理和掘进工艺落后.由此对金属支架构造和巷道掘进工艺的合理改进,不但降低了掘进成本,也提高了掘进单进度及巷道质量标准化,保证了矿井采掘正常衔接,取得了良好的经济效益和社会效益.

Application of fuzzy mathematics in improving driving support parameters

The main factors affecting roadway driving can be estimated roundly and impersonally by using the synthetic appraisal method of fuzzy mathematics. In this paper, based on actual investigation and research, the main factors that influence the driving support of roadway, which are the unreasonable support structure of metal and the backward driving techniques, are found by applying the synthetic appraisal method of fuzzy mathematics. So, by reasonably improving the support structure of metal and the driving techniques of roadway, the driving costs are decreased. The driving rate and quality standardization of roadway are increased. The good economic benefit and social benefit are obtained.
