Geological mechanics tests are carried out on No.18209 roadway with large-section in XieGou ditch coal mine, and the law of geostress distribution is analyzed.The new support scheme is used to solve the problem during supporting, by comparison the traditional scheme of which the bolts and cables are usually hard to be perfectly matched, provides a scientific and reasonable support scheme for the roadway excavation in the coal mine.The application improves the support strength of roadway surrounding rock, and reduces the material consumption and maintenance cost, which is of great significance for the production.%对斜沟煤矿18209大断面掘进巷道开展地质力学测试,并分析了地应力分布规律.应用新型支护材料,并通过新旧支护方案的对比,得出新型支护方案解决了锚杆、锚索各构件合理配套问题,从而为斜沟煤矿掘进巷道提供科学合理的支护方案,显著提高了巷道围岩支护强度,减少了掘进时期及后期维护材料消耗,对斜沟煤矿节支降耗具有重要意义.
