摘　　要：Wilson强度理论在条带开采的煤柱稳定性校核中得到广泛运用,稳定性校核结果可以满足生产需要。常规条带开采中,煤柱稳定性校核可以运用该理论的简化公式,当煤柱两侧开采参数不同时,需要灵活运用该理论进行煤柱稳定性校核与分析。对非常规条带煤柱的主要特征进行了说明,从Wilson强度理论的基本原理出发,得出了非常规条带煤柱稳定校核公式,并结合具体工程实例,运用公式进行了非常规条带煤柱稳定性的校核。Wilson strength theory has been used widely in coal pillar strength check of strip mining whose result can meet mining re-quirement.In conventional strip mining, simplified formula of this theory can be used.When mining parameters of two sides of coal pillar were different, flexibility was needed to check coal pillar stability with this theory.This paper introduced main characteristics of unconventional strip coal pillar, from basic principle of Wilson strength theory, the check formula of unconventional strip coal pillar stability was obtained.In practice, this formula was applied to checking coal pillar stability of unconventional strip mining.
