Based on the engineering geological conditions of a coal mine in western China, this research focuses on addressing the challenges associated with rock burst prevention in working face of inclined thick coal seams. Theoretical analysis, mechanical modeling, numerical simulation, and field monitoring were employed to analyze the influencing factors and hazardous areas of rock burst in working face of an inclined thick coal seam. Optimization strategies for double entry inward layout were proposed and subsequently validated through engineering application. It is found that the occurrence of rock burst is influenced by several factors including buried depth, thick-hard roof, coal seam dip angle, coal pillars, bottom coal. The belt and track roadways were identified as zones with strong rock burst danger, while the setup entry was categorized as a zone with moderate rock burst danger. Based on an analysis of roof structure evolution and floor stress calculations, the floor was divided into three low-stress zones: the semi-protected zone beneath key blocks (I), the protected zone beneath key blocks (Ⅱ), and the stress release zone of gangue (Ⅲ). Numerical simulations determined that the optimal positioning was within the protected zone beneath key blocks (Ⅱ), specifically at a horizontal distance of 5.15 m from the right of the track roadway and a vertical distance of 3 m from the goaf. Microseismic and pressure monitoring demonstrated that implementing the double entry inward layout transformed the energy release pattern of the surrounding rock from "low-frequency and high-energy" to "high-frequency and low-energy". Furthermore, the duration of continuous pressure was significantly reduced, thereby mitigating the rock burst danger in the working face.

针对倾斜厚煤层工作面冲击地压防治难题,以西部某煤矿工程地质条件为背景,采用理论分析、力学模型、数值模拟和现场监测等手段开展细化研究;分析倾斜厚煤层工作面冲击影响因素和危险区域,提出双巷内错布置的防冲优化方案并进行工程验证。结果表明:埋深、硬厚顶板、倾角、煤柱及底煤对冲击地压的发生有影响,确定工作面胶带巷和轨道巷为强冲击危险区,开切眼为中等冲击危险区;结合顶板结构演化与底板应力计算将巷道底板划为关键岩块半保护区(Ⅰ)、关键岩块保护区(Ⅱ)和矸石让压区(Ⅲ)共计3个低应力区;通过数值计算得出内错胶带巷的最佳布巷位置位于关键岩块保护区(Ⅱ),即与轨道巷右帮水平距离5.15 m,与采空区垂直距离3 m。通过微震及来压监测得出,采用双巷内错布置方案后,工作面围岩能量释放由“低频高能”向“高频低能”转变,且持续来压时间明显减短,降低了工作面发生冲击的危险性。

针对倾斜厚煤层工作面冲击地压防治难题,以西部某煤矿工程地质条件为背景,采用理论分析、力学模型、数值模拟和现场监测等手段开展细化研究;分析倾斜厚煤层工作面冲击影响因素和危险区域,提出双巷内错布置的防冲优化方案并进行工程验证。结果表明:埋深、硬厚顶板、倾角、煤柱及底煤对冲击地压的发生有影响,确定工作面胶带巷和轨道巷为强冲击危险区,开切眼为中等冲击危险区;结合顶板结构演化与底板应力计算将巷道底板划为关键岩块半保护区(Ⅰ)、关键岩块保护区(Ⅱ)和矸石让压区(Ⅲ)共计3个低应力区;通过数值计算得出内错胶带巷的最佳布巷位置位于关键岩块保护区(Ⅱ),即与轨道巷右帮水平距离5.15 m,与采空区垂直距离3 m。通过微震及来压监测得出,采用双巷内错布置方案后,工作面围岩能量释放由“低频高能”向“高频低能”转变,且持续来压时间明显减短,降低了工作面发生冲击的危险性。

Based on the engineering geological conditions of a coal mine in western China, this research focuses on addressing the challenges associated with rock burst prevention in working face of inclined thick coal seams. Theoretical analysis, mechanical modeling, numerical simulation, and field monitoring were employed to analyze the influencing factors and hazardous areas of rock burst in working face of an inclined thick coal seam. Optimization strategies for double entry inward layout were proposed and subsequently validated through engineering application. It is found that the occurrence of rock burst is influenced by several factors including buried depth, thick-hard roof, coal seam dip angle, coal pillars, bottom coal. The belt and track roadways were identified as zones with strong rock burst danger, while the setup entry was categorized as a zone with moderate rock burst danger. Based on an analysis of roof structure evolution and floor stress calculations, the floor was divided into three low-stress zones: the semi-protected zone beneath key blocks (I), the protected zone beneath key blocks (Ⅱ), and the stress release zone of gangue (Ⅲ). Numerical simulations determined that the optimal positioning was within the protected zone beneath key blocks (Ⅱ), specifically at a horizontal distance of 5.15 m from the right of the track roadway and a vertical distance of 3 m from the goaf. Microseismic and pressure monitoring demonstrated that implementing the double entry inward layout transformed the energy release pattern of the surrounding rock from "low-frequency and high-energy" to "high-frequency and low-energy". Furthermore, the duration of continuous pressure was significantly reduced, thereby mitigating the rock burst danger in the working face.
