摘　　要：采用FLAC3D三维数值计算分析;应用YTL-130型圆图自记仪、HC-45型压力盒、JSS30A收敛计,对回采工作面实施矿压观测;采用MCJ-10锚杆测力计、CM-12测力锚杆对顺槽巷道锚杆工作状态及力学性能进行测试。通过对观测数据处理分析,研究工作面矿压显现规律及采动对顺槽巷道支护的影响规律。评价整体悬移支架的适用性,分析锚杆支护结构的合理性。从而,评价巷道支护现状与采动影响因素,优化巷道锚杆支护参数,为煤矿安全生产管理提供科学依据。In this study the FLAC3D non-linearity large program was used. On the basis of the pressure observation and measurement by YTL-130 Automotive Drive Recoder, HC- 45Manometer,JSS30A convegence meter,MCJ-10 dynamometer for bolt and CM-12 dynamometer bolt, the characteristic of the tunnel surrounding rock deformation and the bolt stress distribution were analyzed and the bolting support and the stabilization of tunnel were estimated. The reasonable support parameters and improvement about bolting design were reached. This study provides the scientific basis for safety management of coal mine.
