通过力学分析对比了长壁工作面过平行空巷、斜交空巷期间工作面顶板的稳定性、支承压力分布规律。通过相似模拟，研究了工作面过空巷顶板下沉规律。研究表明，工作面过斜交空巷和调斜工作面过空巷能够较好地改善围岩应力环境，降低围岩控制的难度。
通過力學分析對比瞭長壁工作麵過平行空巷、斜交空巷期間工作麵頂闆的穩定性、支承壓力分佈規律。通過相似模擬，研究瞭工作麵過空巷頂闆下沉規律。研究錶明，工作麵過斜交空巷和調斜工作麵過空巷能夠較好地改善圍巖應力環境，降低圍巖控製的難度。

By mechanical analysis, stability and abutment pressure distribution of roof were compared when long-wall working face passing parallel abandoned tunnel and oblique crossing abandoned tunnel. Subsidence of the roof was studied by similar simulation. The results show that, when the working face passes the oblique crossing abandoned tunnel or the abandoned tunnel after slope adjustment of the working face, stress environment of the surrounding rock can be improved and its control difficulty also decreases.
