摘　　要：针对202综放面地质条件,运用理论计算和数值模拟分析的方法初步确定窄煤柱合理宽度为5 m,通过现场矿压实测分析表明,煤柱宽度为5m是合理的,为天池煤矿综放沿空掘巷窄煤柱宽度合理留设提供了可靠依据,并为类似条件下窄煤柱合理宽度留设提供了借鉴。The theory and numerical simulation method were applied to analyze the rational width of the narrow coal pillar for the geological conditions of 202 fully mechanized caving face,and the rational width was initially set up to 5 m. On-site mining pressure measured analysis showed that the coal pillar width of 5 m was reasonable. It provided reliable basis for deterning the rational coal pillar width of Tianchi Mine, and the results could privide the certain guidance to set the rational width of narrow coal pillar for driving groadway along goal at the fully mechanized coal mining face under the similar conditions.
