井下水文地质观测工作,应随矿井巷道掘进和回采工作同时进行,其观测的主要内容包括哪些方面的问题?

答案

参考答案:

①含水层观测:当巷道通过含水层时,应详细地记述其厚度、岩性、裂隙或岩溶发育情况、揭露点的标高、涌水量、水压及水温等,必要时取水样进行水质化验。

②岩层裂隙发育调查及观测:对巷道穿过的含水层,应进行裂隙发育情况调查,记述裂隙的产状要素、长度及宽度、成因类型、张开的或闭合的、充填程度及充填物的成分、地下水活动痕迹及裂隙的消失情况等,并选择有代表性地段测定其裂隙率。

③断裂构造观测:断裂构造往往是地下水活动的主要通道。当巷道揭露断层时,首先确定断层的性质,同时测量断层的产状要素、落差、断层带的宽度、充填物质及其透水情况等,并一一作出详细记录。

④出水点观测:随着矿井巷道掘进或回采工作面的推进,发现有出水现象,水文地质技术人员应及时到现场进行观测。观测的内容包括出水时间、地点、出水层位、岩性、厚度、出水形式、水量、水压、标高、出水点围岩及巷道的破坏变形情况等,找出出水原因,分析水源,有必要时应取水样进行化验。对上述内容应作详细记录,编制出水点记录卡片,并绘制出水点素描图或剖面图及出水点水量变化曲线图。

A scientist turns out to be able to see the future by offering each of some four-year-olds a piece of candy and watching how he or she deals with it. Some children reach eagerly for the treat they see. Some last a few minutes before they give in. But others are determined to wait until the last moment.

By the time the children reach high school, something remarkable has happened. A survey found that those who as four-year-olds had enough self-control to hold out generally grew up to be more popular, adventurous, confident and dependable. The children who gave in to temptation early on were more likely to be lonely, easily frustrated and inflexible .

Actually, the ability to delay reward is a sign of emotional intelligence which doesn’t show up on an IQ test.

The hardware of the brain and the software of the mind have long been scientists’ concerns. But brain theory can’t explain what we wonder about most, like the question why some people remain upbeat in the face of troubles that would sink a less resistant soul.   

Here comes the theory of Daniel Goleman, writer of Emotional Intelligence: when it comes to predicting people’s success, brain ability as measured by IQ may actually matter less than the qualities of mind once thought of as “character”.

EQ is not the opposite of IQ. What researchers have been trying to understand is how they work together; how one’s ability to handle stress, for instance, affects the ability to concentrate and put intelligence to use. Among the elements for success, researchers now generally agree that IQ counts for about 20%; the rest depends on everything from social class to luck.

While many researchers in this relatively new field are glad to see emotional issues finally taken seriously, some few fear EQ invites misuse.
