1966年云南东川6.5级地震的热异常时空结构分析

本文分析了１９６６年云南东川６．５级地震前后浅层地温异常的时空结构及降水异常的水平结构。分析表明，震前数月浅层地温稳定维持正异常，发震前一个月激剧增温，发震当月达最大，震后降低；震前震中区为负地温距平区，随发震时刻临近，负距平区迅速演变为正距平区，而且强度和面积都不断增大，至发震时达最大，震后不断减小；热异常是从深层传向地表的；震中区震前为旱区，震后为涝区。本文还讨论了震源处热信息传到地表的条件和可能机制，认为在水热活动异常的断裂带上，至少对于浅源地震，对流传热是一种较为可能的传热机制。

The Operational Forecasting of Total Precipitation in Flood Seasons (April to September) of 5 Years (1983-1987)

Ⅰ.INTRODUCTION We have discovered that there exists a good corresponding relationship between theanomalous axes of soil temperature at a depth of 1.6m in winter (December to February) andprecipitations in following flood season (Tang et al., 1982a). We have also designed a simplethermodynamical model and applied it to the forecasting of precipitations in the flood season(Tang et al., 1982 b,c). The practical forecast started from 1975. Before 1980, however, therewere only 40-50 stations in China for measuring the soil temperature at a 1.6m depth. Since1980, the stations have been increased to a total of about 180, but no available mean valueshad been obtained from newly added stations before 1982. Therefore the analysis and map-ping of anomalies of soil temperature was not performed until 1983, and from then on theprecision of analysis has been greatly improved. The following is the actual situation of forecast in five years from 1983 to 1987.     

地震预报确定率、报准率和成功率的计算

本文提出一种评价地震预报意见的定量化方法。对于任一种预报意见的确定率、报准率和成功率均以数学公式表示。最后以1975～1984年我国年度地震趋势预报意见为例,进行了计算和分析。结果表明我国的地震中期预报水平还很低。     

甘孜地区古地震遗迹的初步研究

本文所指的甘孜地区是指我国四川省西北部甘孜高原西部的甘孜—马尼干戈断裂带、甘孜—理塘断裂带北段以及鲜水河断裂的北西段所展布的范围。作者于1982年对该断裂的近代构造活动性进行了调查,在调查中发现了一些古地震遗迹,现报导如下: 1.甘孜地区地震地质构造背景该区处于青藏高原的东北缘,区内发育一些近于平行和相互斜交的北西向断裂构造(图     

Roof bolting in underground mining: a state-of-the-art review

Conclusions With continuing investigations and developments, roof bolting today can in most cases successfully reinforce the mine roof in underground mining. In order to cope with the increasing use of roof bolts, efforts should be made to maximize the safety and minimize the cost. With regard to mechanical bolting, two important parameters need more advanced improvements and study, namely, optimum design of the shape and type of expansion shell and optimum bolt tension for a specific bolt pattern. For the fully grouted resin bolt, the most critical requirement is to develop a fast-setting, low-cost, intoxic, inflammable grouting material that can be used in the high speed mining cycle. It should be noted that geological conditions such as the strata type, rock properties,in situ stress, and planes of weakness play an important role in the successful application of any roof bolting system. These factors should be specified as accurately and quantitatively as possible in the design of any roof bolting system. Finally, proper and careful installation and continuous monitoring are imperative for the success of any roof bolting system.     

Main genetic types of Ni ore deposits in China and their relations to paleo-plate tectonics

So far three main genetic types of nickel deposit have been recognized in China: magmatic copper-nickel sulfide deposits, nickel deposits occurring in the crust of weathering, and sedimentary nickel deposits. On the basis of the geotectonic settings of intrusive bodies, their genetic types, and the way sulfides are concentrated, the copper-nickel sulfide deposits fall into two broad categories: deposits emplaced along paleolandmass edges and those in the mobile zones on the outside of paleolandmasses. They can further be divided into six sub-categories and then a variety of types. The magmatic copper-nickel sulfide deposits constitute one of the most important genetic types in China. Geological evidence shows that the individual ferruginous ultrabasic bodies intruding along paleolandmass edges are most favourable for Ni-mineralization. In the light of the paleo-structural analysis, the author has proposed three mechanisms with respect to the formation of Ni-bearing ultrabasic bodies.
