摘要
介绍了小康矿极软岩、易自燃的厚煤层特点 ,针对煤层赋存状况及自然地质条件 ,围绕综放面两巷软岩支护问题做了大量的研究和实践 ,取得较好的效果 ,确保了“一矿一面” ,实现了高产高效。
Characteristics of very soft rock and combustible thick seam in Xiaokang coal mine are introduced.Based on present coal seam situation and natural geology condition,problems of two_roadway timbering at comprehensive mechanization caving coalface,a large number of research and practice are carried out,and better result are obtained to ensure high_production & high_efficient.
