煤矿井下安全回采工艺研究

Study on safe mining technology in coal mine

我国煤炭资源丰富,谋炭赋存条件复杂,井下回采工作面经常遇到大断层。预掘巷道法是回采面过断层的一种有效技术手段,所以,我们必须立足实际情况,选择合适的回采工艺,掌握开采要点,针对不同地质类型做出合理的回采方案。

Our country is rich in coal resources,and the conditions of seeking carbon are complex.Large faults are often encountered in underground mining face.Pre-excavation roadway method is an effective technical means of crossing faults in mining face.Therefore,it is necessary to be based on the actual situation,select appropriate mining technology,master the main points of mining,and make reasonable mining plan according to different geological types.
