自制水压支柱在缓薄矿脉深井开采中的试验与应用

摘要

The working principle and technical characteristics of self-made hydraulic props and the calculation formulas for the smallest setting load,the increment of the sustaining vesistance and the rated sastaining resistance which are closely related to the practical application of the prop are presented.Further description is made on the application and testing results of hydraulic prop in the deep well mining of slowly inclined thin ore vein.%介绍了自主研制的水压支柱的工作原理和技术特性，给出了与实际运用密切相关的最小初撑力、工作阻力增量和额定工作阻力的计算公式。还进一步介绍了水压支柱在深井缓倾斜薄矿脉开采中的使用情况和一些测试结果。
