在测绘学科中,当地下资源开采中和开采后,为更好地监测和研究内部岩层和地表的沉陷规律,除采用常规的测量仪器进行地表和内部岩层位移量监测外,还可采用国际通用的岩土工程专业软件进行模拟、分析和计算。本文通过分析断层影响下的地表移动变形特征实测资料,利用有限元分析软件 FLAC,就大倾角逆断层条件下开采引起的地表移动破坏规律进行了重点分析,提出了该地质条件下地表和围岩移动变形发展的趋势,尤其是在岩层内部和断层露头处的移动变形分析结论,对观测点、线的布设提供了指导,是地表和围岩观测的有益补充,同时为矿区及类似条件下“三下一上”采煤技术的研究提供了可靠的依据。
在測繪學科中,噹地下資源開採中和開採後,為更好地鑑測和研究內部巖層和地錶的沉陷規律,除採用常規的測量儀器進行地錶和內部巖層位移量鑑測外,還可採用國際通用的巖土工程專業軟件進行模擬、分析和計算。本文通過分析斷層影響下的地錶移動變形特徵實測資料,利用有限元分析軟件 FLAC,就大傾角逆斷層條件下開採引起的地錶移動破壞規律進行瞭重點分析,提齣瞭該地質條件下地錶和圍巖移動變形髮展的趨勢,尤其是在巖層內部和斷層露頭處的移動變形分析結論,對觀測點、線的佈設提供瞭指導,是地錶和圍巖觀測的有益補充,同時為礦區及類似條件下“三下一上”採煤技術的研究提供瞭可靠的依據。

In surveying and mapping science,during or after the exploitation of the underground resources,in order to do better on monitoring and studying the law of internal rock strata and surface subsidence,in addition to monitor the displacement of the surface and internal layers by using conventional measuring instrument,and we can also use the professional software of geotechnical engineering for simulation,analysis and calcula-tion.This paper analysed the measured data of the surface movement deformation characteristics by using the finite element analysis software FLAC,and analyzed the destruction rule of surface movement for special mining under the condition of large angle and reverse fault,put forward the development trend of the surface and sur-rounding rock’s deformation under that condition.The movement and deformation conclusion of the internal rock and the fault outcrop,provides guidance for the observation points and the lines’layout,which is a bene-ficial supplement to the observation of the earth's surface and surrounding rock,and at the same time,provides the reliable basis for the Study of coal mining technology under water body,building and rail,and on karst wa-ter body.
