Based on the accumulation of the geological and geophysical data for many years, the geological interpretation on the regional gravity and magnetic anomalies in Nanling area of southern China is put forward in this paper as follow: Ⅰ. There are distinct gravity and magnetic anomalies indicating the fracture tectonics, and the enormously extensive gravity gradient indicating the large fracture zone at depth. On these grounds, in accordance with the extension and distribution of the fractures, they can be classified into four fracture series, namely, (1) Wuling Mount fracture series; (2) Hunan—Guangxi fracture series; (3)Wuyi Mount fracture series; (4)Pearl River—Chaozhou—Shantou fracture series. And they are specifically divided into 41 fracture zones to provide geophysical basis for the investigation of fracture tectonics in Nanling area. Ⅱ. It is capable to lay stress on the effect of the geological factors at depth, and reduce the interferences resulted in the complex geological features on the surface in dividing the geotectonic elements by regional gravity and magnetic anomalies. Due to the inadequate details of the current gravity and magnetic data, the geotectonic elements are divided up to third order in this paper. It would not be favorable to advance the more detail classification until much more informations would have been accumulated. Ⅲ. The regional ore-controlling fraetors for some endogenetic metallic deposits can be distinguishedly reflected by the regional gravity and magnetic anomalies: 1. All the large ore fields are located on the gravity gradient zone, and in many cases associated with clear negative gravity anomalies. This characteristic of the gravity field represente two types of geological features: (1) The gravity gradient zone indicates the occurrence of large fracture at depth. (2) The local negative gravity anomalies are in many cases caused by hidden and semi-hidden granite masses. Both geological features mentioned above play an important role in ore formation. 2. Covering almost all the large endogenetic metallic deposits there are distinct local aeromagnetic anomalies. 3. Aeromagnetic "high magnetization zone", indicating the large extention of mineralization and alteration, is an important criteria for minerogenetic prognosis. 4. The hidden rock mass and granitic contact alteration zone which are reflected by the gravity and magnetic anomalies can afford the favorable spatial position of ore formation for minerogenetic porgnosis. 5. Being able to sieve the mineralized and altered fracture zones out of the numerous ones on the surface, the chain of the short-axis aeromagnetic anomalies are of great significance for minerogenetic prognosis. In general, the specific geological conditions are needed for the formation of large-scale ore deposits. It follows that the geophysical anomalies will correspondently be induced by the specific variations of the geological factors. On the basis of the regional gravity and magnetic anomalies we obtained reflecting some regional ore-controlling factors, on which a rather detailed demonstration has been given, and a viewpoint on minerogenetic prognosis has also been proposed in this paper. Therefore, it is worth for reference in reconnaissance survey and prospecting in Nanling area henceforth.

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。
