低沼矿区煤层气体地化特征及其灾害性

用立体地球化学的观点和方法研究了徐州煤田“低沼矿区”的瓦斯问题可以获得“低沼矿区”煤层气体是以甲烷为主,重烃含量甚低,δ~(13)C_1偏负等特征,并指出:低沼矿区具有相对性的特点,在一定条件下,煤层仍可具一定的气体灾害性。另外,用碳同位素方法还可以判别“煤层气体的活性”,以反映煤层气体和地下水的灾害倾向性。

Disasters in Bangladesh

This paper deals with various types of natural disasters which occur very frequently in Bangladesh. Disaster can occur at any time, in any place, in any dimension, and may owe as much to the circumstances as to the scale of the event. With the exception of the man-made disaster of war, famine, fire, pollution, accident and civil strife, the worst disasters follow natural events.Bangladesh is widely known as a land of natural disasters and is highly vulnerable to flood, cyclone and river erosion. By the effects of these disasters the country is now permanently in distress. These disasters have become a regular phenomenon and cause suffering to millions of people of the country since many decades. Besides, it also focuses on policy options concerning disaster management.

Seismic hazard analysis for a spatial linearly distributed system

The models currently used in the seismic evaluation of important projects, microzoning and seismic zonation are all for site. Although seismic hazard analysis have been done for many sites in seismic zonation and microzoning, relationship among sites is not considered in the final results. Studies show that it is impossible to get total hazard for specific area from the results of the hazard analysis of sites. So, when we consider the total seismic hazard of a specific spatial distributed system, methods for site are not enough. Author discussed the relation and the difference between system hazard and segments hazard which form the system and proposed a seismic hazard analysis model taking spatial linear distributed series and parallel system as an example. In aseismic design and earthquake disaster prevention decision, not only the seismic hazard of segments of the system but also the total seismic hazard of the system should be considered. The Chinese version of this paper appeared in the Chinese edition ofActa Seismologica Sinica,15, 347–352, 1993.
