浅埋煤层沟壑区塌陷灾害形成机理分析研究

Analysis and Study on Formation Mechanism of Subsidence Disaster in Gully Region of Shallow Depth Seam

针对冯家塔煤矿地表沟壑纵横切割和浅埋煤层的特殊采矿、地质、地形条件进行分析,在1201工作面现场调查数据的基础上,结合开采地表塌陷灾害情况,进行了相似材料模拟实验和计算机数值模拟分析,给出了冯家塔煤矿开采引起沟壑边坡崩塌、滑坡灾害的特点并分析了其形成机理,提出了灾害治理措施,为矿区安全生产和可持续发展提供了保障,为同类矿区开采条件下开采沉陷灾害防治提供了可靠的科学依据。

According to the analysis on the special mining, geology and topography conditions of the crossed gully cutting surface and the shallow depth seam in Fengjiata Mine, base on the site investigated data of No. 1201 coal mining face, in combination with the surface subsidence disaster conditions occurred by the underground mining, a similar material simulation experiment and the computer numerical simulation analysis were conducted. The paper provided the gully slope collapse, the landslide disaster features caused by the mining of Fengjiata Mine and the formation mechanism was analyzed. The disaster control measures were provided in order to provide the protections of the safety production and sustainable development of the mining area and to provide reliable scientific basis to the prevention and control of the mining subsidence disaster under the mining conditions in similar mining area.
