摘　　要：通过对采煤工作面初次放顶期间矿压观测数据微机处理，总结特种支架的工作特性及其作用；并探讨单体液压支柱对初次放顶期间顶板活动规律的适应性，表明采煤工作面初次放顶期间可以取消特种支架。石台煤矿的生产实践亦证明，在一般条件下无特种支架初次放顶技术可行、安全可靠、经济合理。y means of micro-computerized process of theobservd data of ground pressure during the initial cavingof the roof at coal faces.the work performance andfunctions of the special supports were summarized and theadaptability of single hydraulic props to the activityregularity of the roof at coal face during the initial cavingwas studied.They indicate that the special supports are notnecessary during the initial caving of the roof.Again,thefield practice at Shitai mine has proved that during theinitial caving,generally,the technique of initial cavingwithout special supports is feasible,reliable andeconomical.
