Some major technical problems and countermeasures for deep mining

摘要

The key technical issues in deep mining were analyzed and some corresponding solutions were presented as follows: firstly, control gas to prevent outburst of gas and coal; secondly, improve the surrounding rocks controlling technique to limit the amount of the distortion; thirdly, control the temperature of deep mining by the means of cooling technique; finally, change the concentrated stress to prevent rock burst. In a word, it reduces and prevents the danger of deep mining by inspiring innovation in scientific and technological research, continuously improving and optimizing mining process and adopting the advanced technique and equipment.
