摘要
通过利用GSJ-1型矿压仪和DZ-WCI型单体液压支柱工作阻力检验仪等对宝雨山煤矿11103和11108放顶煤工作面进行了全面的矿压观测和研究。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。通过对采煤工作面所使用的支护设备的可靠性和适应性进行评价,为工作面设备的改进与更新提供参考;确定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依据。
hrough using the GSJ-1 rock pressure equipment and the DZ-WCI hydraulic prop yield load inspection instrument and steel tape to proceed full measuring of rock pressure in 11103 and 11108 sub-level caving mining by the BaoYushan coal mine. The character of the roof movement law , the presentation law of rock pressure and the roof control are grasped .Through which assess against reliability and adaptability of support equipments what are used in working face, supply reference for improving and refreshing of equipment, define the picked movement incidence and the distribution rule of the supporting pressure, choose the reasonable support way.
