朋友,您知道煤炭是怎样开采出来的吗?或许有人回答,是用圆木支撑顶板,放炮落煤,最后用矿车将煤炭运至地面的。 如果在二十年前的话,这种说法没有错。可是,在人类已经进入信息化社会的今天,煤矿,特别是国有重点煤矿,上面所说的“炮采车运”的采煤方法还真的不多见了。 几十年来,特别是实行改革开放的二十年,我国在煤矿采煤方法上不断探索研究,积极借鉴国外发达国家的先进采煤经验,走出了一条具有我国特色 Friend, do you know how coal is mined? One might answer that it is to support the roof with round logs, fire the coal and finally bring the coal to the surface with a mine car. If twenty years ago, this is not wrong. However, at a time when mankind has entered an information society, coal mines, especially the state-owned key coal mines, are really rare in the coal mining methods mentioned above. In the past two decades, especially in the two decades of carrying out the policy of reform and opening up, China has continuously explored and studied coal mining methods and actively learned the advanced coal mining experience of developed countries in the world.
