| 摘 要： | 根据影响岩体稳定性因素,结合钻孔揭露资料,应用单因素分析和模糊综合评判法研究了51-72煤层段岩体的稳定程度。研究表明,51-72煤层段岩体以碎裂和散体结构为主,褶皱发育程度以中等发育为主,岩石单向抗压强度在30~45MPa间占60%以上,主要属粉砂岩-泥岩沉积区;51-72煤层段岩体稳定性以极不稳定和不稳定为主,约占65%,较稳定的约占25%,稳定的仅占10%。评价结果与矿井实际揭露情况基本一致,为巷道布置、支护形式选择等提供了依据。 |

| Abstract: | According to the factors influenced to the rock mass stability and in combination with the released information of the drilling boreholes,the single factor analysis and fuzzy comprehensive evaluation method were applied to study the stability degree of the rock mass in 51-72 seam section.The study showed that the rock mass in 51-72 seam section would be mainly in fracture and loose structure,the folded development degree was mainly in medium development,the unidirectional compressive strength of the rock wa... |
| Keywords: | rock strata in seam section fracture dimension value double weight quantitative evaluation |
