掘进保证系数──一种衡量采掘平衡的新指标

Coefficien of Drivage Assurancea New Index for Testing Balance of Preparation and Winning Work

针对三量可采期等传统指标的通用性差等问题，研究了煤矿的采掘平衡关系，提出了一种新指标──掘进保证系数．该方法结合采掘计划可以动态、准确地反映矿井现在及未来的采掘关系．在江苏某矿务局的应用结果表明，该方法能够准确反映掘进对回采的保证情况．

A new index-coefficient of drivage assurance is put forward by studying the relationship of extraction and drivag for overcoming the shortcomings of traditional indexes on balance of preparation and winnin work.ms method combtoed with mining plan can dynamically renect the situation of preparaion and winnin work..Practice in one of mining bureau's five mine proved tha this method can effectively detennin if the drivag can ensure extraction.
