探水前应该注意哪些问题?

答案

参考答案:

探水作业是直接与水害作斗争,不仅关系到探水人员的安全,而且关系到探水周围地区甚至整个矿井的安全。因此,在探水地点开始前,应注意以下问题:

1、加强靠近探水工作面的支护,以防治高压水冲跨煤壁和支架。

2、检查排水系统,根据预计出水量安装足够能力的排水设施,清理巷道浮煤,挖好排水沟。

3、水压较大时,探水孔要设套管,以便安装控制阀。特别危险的地区要在坚固地点砌筑水闸墙。

4、探水地点或附近要安设专用电话,以便与调度室和中央泵房直接联系。

5、探水工作面要经常检查瓦斯和其他有害气体。

6、制定、检查安全撤退路线,使其畅通无阻,万一突水,保证工作人员顺利撤离险区。

7、探水孔的位置、方位、角度、钻孔数及钻进深度等参数,应有测量人员和负责探放水人员亲临现场,共同确定。

Why do people drink too much, eat too much, smoke cigarettes or take drugs? What’s to blame for all the bad behavior? Most people would say that, while these self-destructive (自我毁灭的) acts can have many root causes, they all have one obvious thing in common: they are all examples of failures of self-control, lacking the will power to resist them.

According to a recent study, however, if you really think about it, something about that simple answer doesn’t quite make sense. In fact, it turns out that sometimes it’s having will power that really gets you into trouble.

Think back to the time you took your very first sip (啜饮) of beer. Disgusting, wasn’t it? When my father gave me my first taste of beer as a teenager, I wondered why anyone would voluntarily drink it. And smoking? No one enjoys their first cigarette — it tastes awful. So even though smoking, and drinking alcohol or coffee, can become temptation (诱惑) you need will power to resist, they never, ever start out that way.

Just getting past those first horrible experiences actually requires a lot of self-control. Ironically (讽刺的是), only those who can control themselves well, rather than give in to them, can ever come to someday develop a “taste” for Budweiser beer, Marlboro cigarettes, or dark-roasted Starbucks coffee. We do it for social acceptance. We force ourselves to consume alcohol, cigarettes, coffee and even illegal drugs, in order to seem experienced, grown-up, and cool.

These bad habits aren’t self-control failures — far from it. They are voluntary choices, and they are in fact self-control successes. Self-control is simply a tool to be put to some use, helpful or harmful. To live happy and productive lives, we need to develop not only our self-control, but also the wisdom to make good decisions about when and where to apply it.
