水力采煤在通化矿区的发展及前景展望

Development and Perspective of Hydraulic Coal Mining at Tonghua Mining Area

通化矿区煤田地质构造极其复杂，开采困难。通过多种采煤方法的试验、比较后，找到了一种对复杂煤层适应性较强的采煤方法——水力采煤方法。经过二十来年的生产实践，水采技术不断完善和提高，收到较好的经济效益。并在此基础上提出今后采用经济型水采工艺、节能降耗、发展高档水采的努力方向。

Extremely complicated geological conditions in the mining area causes difficulties in mining. Finally hydromining method, an appropriate method suitable for use in the area, were found through comparison between various mining methods. Over the past 20 -odd years,the mining technology has been continuously updated,bringing forth more favourable economic result. Efforts are being made towards the development of district-based economy mining system for saving energy.
