Ground fissures accelerate land degradation and soil erosion, and induce secondary geological disasters such as landslides and collapses. To reveal the development characteristics of ground fissures under high-intensity mining conditions, relevant research was carried out with the 615 working face of a mine as the engineering background, and multiple methods including field measurement, experimental simulation, theoretical analysis and engineering application were comprehensively utilized. The results show that ground fissures are mainly divided into tensile, step and collapse types according to different deformation properties. During the advance of the working face, the propagation period of fissures within the working face is shortened and the closure degree decreases. The development degree of ground fissures is more significant than that under conventional geological and mining conditions. The number of fissures with widths of 0-100 mm, 100-500 mm and greater than 500 mm accounts for 38%, 56% and 6%, respectively. Overburden fissures develop synchronously with the breaking of thick and hard rock strata and eventually penetrate the ground surface. Based on the critical deformation values of ground fissures, the fissure angle along the strike, the fissure angle on the dip side, and the fissure angle on the rise side are predicted to be 79.8°, 74.1°, and 79.5°, respectively, with a maximum relative error of 7.1%. In addition, the calculation formula for the critical depth-thickness ratio of through fissures was proposed. The research results are of important reference significance for land remediation and geological disaster prevention in mining areas.

地表裂缝会加速土地退化和水土流失，诱发滑坡、崩塌等次生地质灾害。为揭示高强度开采条件下的地表裂缝发育特征，以某矿615工作面为工程背景，综合采用现场实测、试验模拟、理论分析、工程应用等方法开展了相关研究。结果表明：按变形性质不同，地表裂缝以拉张型、台阶型和塌陷型为主，工作面推进过程中面内裂缝扩展周期缩短、闭合度降低。地表裂缝发育程度相比于一般地质开采条件更强，宽度为0~100 mm、100~500 mm和大于500 mm的裂缝数量分别占38%，56%和6%。覆岩裂缝伴随厚硬岩层破断同步发育，最终贯通至地表。基于地表裂缝临界变形值，预测得到走向、下山和上山裂缝角分别为79.8°、74.1°和79.5°，最大相对误差为7.1%。此外，给出了贯通型裂缝产生的深厚比临界值计算公式。研究成果对矿区土地修复及防治具有重要参考价值。
