简述煤层的可采程度与勘查对象、资源储量估算的关系.

答案

参考答案:

在勘查评价范围内(一般为一个井田或勘查区)可采程度与勘查区面积直接相关。煤层的可采程度与其是否作为勘查对象是否估算资源储量既有联系性质又不完全相同。一般来说全区可采煤层和大部分可采煤层是勘查的主要对象但在资源条件比较差的地区局部可采煤层也可能成为主要勘查对象甚至不可采煤层的某些区段也可能被开采利用。对煤层的可采程度进行划分是为了便于评价和比较而该煤层是否作为勘查对象是否估算资源储量应根据对该煤层的合理利用和开采的经济意义不致造成煤炭资源的浪费或破坏等具体条件确定。

When I was a foreign teacher in China,every day I taught English to my students and they taught me about China.One day the topic turned to saying “I love you”.I was shocked to learn that not one of my students had said this to their mothers,nor had their mothers said it to them.“Does your mom love you?” “Of course,”they answered.

“How do you know it?” was my logical question.They responded that their moms cooked and always told them what they were doing wrong to show their caring.I was strummed. So mom's cooking and criticizing read out as “I love you”. “Then how do you say ‘I love you’ to her?” They agreed that getting good grades, followed by good jobs would be how they showed their love.

I come from a culture where most people are expressive enough,so I repeated these queries in classes over time.Gradually,I began to get different responses.Some of them had exchanged those sentiments with their moms.

One of my favorite stories of change came from a girl.When she came home from university,her mother met her at the door and hugged(拥抱)her.This had never happened before,but her mom said,“Now that you have gone I have more time to myself.”I noticed that in some places mothers and children hug each other and I decided it was a good idea and that I would begin hugging you.”

In my family we all say “I love you” a lot.While it is true that we often say the words without having great depth of feelings at that moment,and it is almost like a blessing we give each other. Those three little words carry a world of meaning,even when said as a greeting, but most especially if they are the last words we say to or hear from those we love.
