1、The high quality talc in Haicheng mine field can be used to many kinds of industry.
2、The feasibility study of longwall with top-caving mining in 3~# coal seam on Wangpo mine field
3、The structural deformation is the principal geological factor that affects the thickness variation of coal seam on a mine field scale.
4、The banded gneisses underlying the mine field are, as a rule, micaceous, the amount of biotite determining mainly the shades of the bands.
5、As a result, for increasing kill efficiency of intelligent mine field to armored aim in group, intelligent mine is supposed to adopt multiple explosively formed penetrator warhead technology.
6、The storage, application and forecast of coal seam gas in Hegang mine field are introduced, and the detailed mining area and way for earlier and later stage are provided.
7、With topographic map and other methods, some class I～V active faults that run through Laohutai mine field in modern stress environment are found out by means of geodynamic zoning.
8、The gas got together, and the technician acted against the rules to weld underground in the mine field. There were more than twenty people killed in the fire damp explosion.
9、"to prevent soldiers from stepping on land mines placed by the Eighth Route Army, more than ten Chinese people were ordered to lead the way, i. e. to walk in the mine field in front of the troops";
