以爆堆形态作为爆破效果的主要评价依据，结合炸药单耗、起爆方式、孔网参数分别对爆堆松散系数与爆堆沉降沟的影响关系进行了多因素综合分析，评价了爆堆形态与各参数的内在联系。研究结果表明：当单耗增加时，爆堆沉降沟深度的增长速率大于松散系数的增长速率；当排距增大时，爆堆松散系数递减较缓，爆堆沉降沟递减速度由快至缓。通过对爆堆形态的多因素综合分析，为爆破优化设计提供了帮助。
以爆堆形態作為爆破效果的主要評價依據，結閤炸藥單耗、起爆方式、孔網參數分彆對爆堆鬆散繫數與爆堆沉降溝的影響關繫進行瞭多因素綜閤分析，評價瞭爆堆形態與各參數的內在聯繫。研究結果錶明：噹單耗增加時，爆堆沉降溝深度的增長速率大于鬆散繫數的增長速率；噹排距增大時，爆堆鬆散繫數遞減較緩，爆堆沉降溝遞減速度由快至緩。通過對爆堆形態的多因素綜閤分析，為爆破優化設計提供瞭幫助。

The form of blasting muck pile is taken as the main evaluation index of blasting effect, combined with the explosive unit consumption,detonation way,parameters of blasting hole arrangement, the influence relationship between loose blasting heap coefficient and blasting pile settlement groove is an-alyzed comprehensively by multi-factors so as to evaluate the internal relationship between the form of blasting muck pile and the above parameters.The research results show that,when the explosive unit consumption increases,the increase rate of blasting pile settlement groove depth is greater than that of loose coefficients;when the row spacing increases,the blasting muck pile loose coefficients declines slo-wer and slower,the decline speed of blasting pile settlement groove depth from fast to slow.The above research results show that,the comprehensive analysis method of blasting muck pile form based on multi-factors is more conducive to optimization and design of blasting.
