Most ores in Jin Shah dian Iron Mine are sandy and easily cave in influence of explosion vibration and in moist air. Metal Supports were used in mining entry of this mine. but most of them had already caved. Now spouting concrete sets are used in this mine. In special geologic of this mine, the ore is supported mainly by the strength of spouting concrete itself not by increasing the strength of ore. It becomes important whether spouting concrete has enough strength to support sandy ore succesfully. The strength and deformation of triple center arch and half circular arch with spouting concrete are measured by loading force radically and vertically. The strength and deformation of spouting concrete are compared with that of spouting concrete with bamboo. The results show that spouting concrete arch with 4-5cm thickness has 32-52~T/m~2 strength and less than 3mm deformation; the strength of spouting concrete with bamboo is elevated greatly: it is suitable using spouting concrete sets in this mine; the drawing in scraper drift sprouting by spouting concrete with stee is more diffircult than that with bamboo. Suggestions for design and construction of spouting concrete sets are also given in this paper.

金山店铁矿的大部分矿体呈粉砂状,在爆破震动影响和潮湿空气中极易冒落。该矿采矿进路曾使用金属支架,但多数已经塌落,现改用喷射混凝土支护,在该矿的特殊地质条件下,这种支护主要靠喷层自身强度支掌矿石,而与矿石共向支护的作用则不显著。因此,薄喷层是否具有足够的承载能力,就成为能否在粉砂状矿体中成功地进行支护的关键。本试验是通过对喷射混凝土三心拱及半圆拱施加径向及纵向荷载来测定其承载能力与变形的,并对素喷射混凝土拱和配竹筋喷射混凝土拱进行了对比。试验结果表明,厚度为4—5cm的喷射混凝土拱具有32~52~T/m~2的承载能力,下沉量均小于3mm,配竹筋后可大大提高其承裁能力;在电耙道中,喷层内配竹筋可减少因配钢筋引起的放矿困难。在该矿位于粉砂状矿体中的采矿进路,采用喷射混凝土支护是适宜的。本文还对喷射混凝土支护设计及施工中的一些问题提出了建议。
