中文摘要：
根据云泉煤矿地面沟谷及山梁发育、相对高差大、埋深多变的支护难题,依据巷道围岩稳定性分类和锚杆支护设计专家系统给出初步锚固方案及参数,运用三维数值模拟软件研究巷道围岩塑性区分布、应力、位移分布规律,并给出了合理的锚固方式与参数。工程实践表明,设计的锚固参数在云泉9号煤条件下是可行的。
英文摘要：
For support difficulties such as valley and ridge development, high relative height difference and being buried deeply and variably, initial bolt-mesh support design and parameters were determined on the basis of surrounding rock stability classification and bolt-mesh support design expert system. 3D numerical simulation software was used to study the distribution, stress, and displacement law in the plastic zone of the surrounding rocks. Reasonable anchorage scheme and parameters were given. Engineering practice showed that the scheme and parameters were feasible in Yunquan mine.
