摘　　要：通过利用GSJ-1型矿压仪、DZ-WCI型单体液压支柱工作阻力检验仪及钢卷尺对宝雨山煤矿11103放顶煤工作面进行了全面矿压观测和研究,掌握了顶板运动规律、工作面矿压显现特征和顶板控制特征.对11103采煤面所使用的支护设备的可靠性和适应性进行了评价,为工作面设备的改进与更新提供了参考;确定了采动影响范围及支承压力分布规律,为合理选择工作面支护方式提供了依据.By using GSJ-1 rock pressure equipment, DZ-WCI hydraulic prop yield load inspection instrument and steel tape to proceed full measuring of rock pressure in 11103 sub-level caving mining of the Bao Yu Shan coal mine. The character of roof movement law, presentation law of rock pressure and roof control are grasped. Through which assess against reliability and adaptability of support equipments which are used in 11103 working face, give reference for improving and refreshing of equipment, define the picked movement incidence and distribution rule of supporting pressure, and choose reasonable support way.
