摘要
以榆树坡公司5^(#)煤首采工作面为研究对象,首先介绍了地质概况和进、回风顺槽施工情况,接着对锚索和锚固剂的黏结强度进行了测试,然后对顶板状况进行了钻孔窥视,并对支护应力场分布进行了分析。由此确定了巷道支护要求和支护参数选取方法,最后提出适宜的支护方案,有效控制了围岩变形。
Taking the first mining face of 5^(#)coal seam in Yushupo Company as the research object,the geological survey and the construction situation of inlet and return air ways were introduced firstly,then the bonding strength of anchor cable and anchor agent was tested,then the roof condition was peeking by drilling hole,and the distribution of support stress field was analyzed.Therefore,the roadway support requirements and support parameters selection method were determined,and the appropriate support scheme was put forward to effectively control the surrounding rock deformation.
