摘要
以金达煤业巷道支护变更为切入点,通过地质力学测试与分析,确定了近距离煤层锚杆支护参数及支护材料,为相似地质条件下的巷道支护提供了一定的理论意义及生产实践应用价值。
Taking changes in roadway supporting of Jinda Coal Industry Co., Ltd. as an example, this paper confirmed the parameters and materials of anchor bolt supporting for close coal seams through the geological mechanics tests and analysis, providing a certain theoretical significance and application value of the production practice for roadway supporting with similar geological conditions.
