摘要
为深刻认识薄煤层特定条件下超前支承压力分布范围及强度规律,以山西某矿10902工作过面为工程背景进行数值模拟,从而为支架选型、支架参数确定、支架改进、支架适应性评价、采煤工艺优化、安全高效生产管理提供技术支撑。
To deeply understand the advance support pressuw distribution scope and intensily regularity at thin seams under certain conditions, this paper can＇ies out numerical sinmlation against 10902 face of Shanxi as engineering background, so as to provide technical support for support selection, support parameter determination, support improvement, support adaptability evaluation, coal mining process optimization as well as safety and efficient production management.
