针对曹家滩煤矿浅埋煤层长距离工作面液压支架选型设计问题，分析浅埋煤层老顶“高位台阶岩梁”液压支架工作阻力计算模型，研究浅埋煤层条件下矿压显现规律，得到工作面液压支架的主要选型特征参数，有效提高了工作面液压支架的可靠性和适用性，为矿井设计提供了技术支撑。

Aiming at the problem of selecting and designing hydraulic supports for long distance working faces in shallow buried coal seams of Caojiatan Coal Mine, this paper analyzes the working resistance calculation model of the "high level bench rock beam" hydraulic support for the old roof of shallow coal seams, studies the law of mine pressure behavior under shallow buried coal seams conditions, obtains the main selection characteristic parameters of hydraulic supports for working faces, effectively improves the reliability and applicability of hydraulic supports for working faces, and provides technical support for mine design.
