摘要: 矿山巷道、交通隧道等地下硐室围岩稳定与岩体所处区域地应力环境息息相关。分析区域深部地应力与地下硐室走向、形状等因素的关系，有助于提前规避硐室开挖风险。文章以山东龙郓煤业10•20冲击地压事故为背景，通过地应力测量与监测工作，初步揭示了山东西部地壳浅表层现今地应力环境，结合龙郓煤业矿区附近现今地应力场特征，探讨此次冲击地压事故产生的区域应力背景，并从地应力角度提出相应的防控建议。研究结果表明：测量深度范围内主应力大小总体上与深度成正比线性关系，最大水平主应力值为3.48~20.76 MPa，随深度增加梯度为0.0182 MPa/m；最小水平主应力值为3.44~14.95 MPa，随深度增加梯度为0.0130 MPa/m；区内最大水平主应力方位为北东43°~89°，平均方位为北东75°；地壳浅表层构造作用以水平构造作用为主，但随着深度的增加，逐渐向垂直构造作用转变；龙郓煤业10•20冲击地压事故的诱发机制主要是垂向应力大于水平主应力，现今处于拉张应力环境，尤其是巷道走向平行于最大水平主应力方向；建议龙郓煤业巷道轴线与最大水平主应力方向的夹角为60°~90°，同时巷道顶板可以采用拱形顶板，确保巷道岩体稳定。Abstract:
Objective The stability of underground chambers such as mine tunnels and transportation tunnels is closely related to the stress environment of the surrounding rock mass and the geological conditions of the area. Analyzing the relationship between deep-seated stress and factors such as the orientation and shape of underground chambers can help to proactively mitigate the risks associated with chamber excavation. Methods This study, set against the background of the rock burst accident on October 20th in the Longyun Coal Industry area in Shandong, reveals the current stress environment of the shallow crustal layers in western Shandong through in-situ stress measurement and monitoring work. Results According to the characteristics of the current ground stress field near the Longyun coal mining area, the study investigates the regional stress background that led to the rock burst accident and proposes corresponding prevention and control suggestions from the perspective of ground stress. The results indicate that the magnitude of the principal stress generally increases linearly with depth within the measurement range, with the maximum horizontal principal stress ranging from 3.48 to 20.76 MPa and a gradient of 0.0182 MPa/m with increasing depth, while the minimum horizontal principal stress ranges from 3.44 to 14.95 MPa with a gradient of 0.0130 MPa/m. The maximum horizontal principal stress azimuth in the area ranges from NE 43°to 89°, with an average azimuth of NE 75°. The tectonic action in the shallow crust is mainly horizontal, but with increasing depth, they gradually transition to vertical. Conclusion The triggering mechanism of the rock burst accident in the Longyun Coal Industry area on 20th October is primarily attributed to the vertical stress exceeding the horizontal principal stress, indicating a current extensional stress environment, especially when the tunnel orientation is parallel to the direction of maximum horizontal principal stress. It is suggested that the angle between the tunnel axis and the direction of maximum horizontal principal stress in the Longyun Coal Industry area should be between 60° and 90°, and that the tunnel roof can be designed as an arch-shaped roof to ensure the stability of the tunnel rock mass. -
