| 摘 要： | 通过对陕北府谷县新民镇小煤矿采煤地表大面积塌陷的调查和分析,总结出黄土丘陵区房柱式开采地表的塌陷特征,并以西岔沟煤矿房柱式开采为例,对其两种参数顶板岩梁应力、煤柱载荷、煤柱强度进行分析及对比,结果表明合理设计煤柱和煤房尺寸可以防止采煤地表大面积塌陷。 |

| Abstract: | Based on investigation into and analysis of the large area ground collapse of small coal mines in Xinmin Town in Fugu County,north of Shanxi,and summarized the features of ground collapse caused by ＂Pillar＂ mining in loess hilly region,the paper took Xichagou coal mine as an example,by analyzing and contrasting the stress of roof rock beam,load and strength of pillar with its two parameters,and the results indicate a reasonable size of room and coal pillar can prevent a large-area ground collapse. |
| Keywords: | loess hilly region room and pillar mining ground collapse mechanism |
