36、2d-实现数值分析。结果展现沉陷曲线和水平线运动曲线并不连续和平滑,由于地质条件的影响,其变化是不对称的。通过分析得出沉陷参数、水平移动参数、顶部下沉量和其他用于预测地面移动的参数。这些参数值与当地采矿条件一致,有助于开采作业。实践证明,研究结果也表明在预测地面移动控制和沉陷灾害预计研究中该理论是成功的。1.简介采煤沉陷中有一个很实际的问题存在了很长的一段时间,它就是关于岩石的毁坏和不连续的破坏分层堆积与地表连续的运动之间的关系。因为复杂的地质学情况和不同的采煤方法没有对应的完全解决问题的办法。在煤层采掘之后,最初形成的压力保持平衡的情况就被破坏了。然后岩石破碎带将会失去稳定并开始不连续地移动

37、或进一步的变形和破坏。而煤层位于建筑物、铁路和水体之下时,该破碎带就必须特别关注。从而引发的地表移动可能引起建筑物损害以及铁路和其他的地面构筑物的损坏。因此它是采煤沉陷中重点调查的问题。地表移动行为在某煤矿(煤层倾向)中的测量、实验和数值分析都将在本文之中学习到。2.常态下的采煤沉陷采煤掘进之后在新的受力情况下地层可以按破坏程度被区分为三个地域,也就是,凹陷地域,破碎地域和弯曲的沉陷地域。岩石在凹陷地域方面包含冒落带,断裂带和整体移动带。在破碎地域中首次出现大的弯曲毁坏地层及垂直和平行破碎的地层。地层连续运动出现在弯曲的沉陷地域,而自其后,破坏分为柔性的和塑性的(不超过毁灭性张力程度)。采煤引

38、起的地层运动被各种不同的地理和采矿因素所影响。因此地层的运动和破坏模型在不同的采煤深度,采煤方法和煤层所处地层情形都是不同的。当厚度和深度比较大时,会发现地层的运动和破坏是连续和有明显规律性的,否则,它们会是不连续和不规则的。水平煤层表现的沉陷盆地和不同的变化或破坏曲线都表现出规律性。至于在煤层倾向层 (也就是,n煤) ,最大的下沉点将会向下山移动但是不会在移动盆地中央出现。沉陷曲线和水平线运动是非对称的。通常,只需要较少工作量的长墙壁采煤法被广泛地采用,地层的沉陷和岩石逐层堆积都沿着煤层的长壁方向发展,最后将保持稳定,与此同时地层的运动规则也是明显的。沿着横断面的地层运动没有明显的规则, 它

39、仰赖特定煤层的地质学情况。以煤层的横断面为基础的研究结果描述见后。3.相似模拟实验3.1建模比建模比就是包括几何学、密度、强度和时间的对比的常数。3.1.1地层的结构类比模拟实验中地层厚度、采矿深度和空间在模型和原型之间必需要遵照精确的比例。在沉陷的模拟中,结构的类似比是一个必要的参数。 通常,比较大的结构类似比能带来更精确的结果。结构的类似比应该是可以做到和理论一样大,但在实际操作上是很困难的。它不仅需要很多的费用 ,而且需要很严谨细致的研究环境。然而,实验准确性要被使用适当的结构类似比影响从而影响适当的尺寸和方法的采用。在如表 1 所显示的,某煤矿考虑实际的情况,样板的实验会深入地下500

40、m的模仿区域。如果结构的类似比比较小,模型就会太大而无法操作, 因此选择的结构类似比是 1 400 。 (cl)表1 煤层中岩石的机械参数 地层 youngs率(mpa)poissons比结合力(mpa)内摩擦角(°)单桥张力(mpa)密度 (t·m-3)tj11064950.342314.5133.42.3297-2.60tf1996390.306016.8122.92.0685-2.45tf21046930.333314.5133.41.9554-2.55pl814774.50.295020.5034.20.7047-2.25pm1120557.50.272714.51

41、33.43.218-2.603.1.2动态类似比动态类似的规则也是需要完全遵照模型和原型之间的精确比例。在实验方面,特性参数包括密度、边界压迫力和强度。建模材料包含沙子、石膏和石灰。 采用的密度比依下列各项cr= h/ = h/ =1.667,式中 cr是密度比; h,在原型和中的1号层的密度及在模型中的1号层的密度。3.1.3掘进时间比.实验期间,模型和原型之间的时间比例界限确定我们采用地心引力在运动学上的类似规则, = = = 20.3.2建模材料目前,普遍采用的建模材料包括石膏混合,石灰混合和合成物质树胶混合等.混合包含辅助和凝结材料。一般的,当石膏和石膏-石灰当做凝结材料用的时候 ,

42、沙子、云母粉和滑石粉被同样地用做辅助材料。考虑到材料的选择,运送,开支和有效性,一般用沙子当做辅助材料,石膏-石灰当做凝结材料。此外,滑石粉层被放置在层之间来模仿实际效果。强度: = /( *) = /666.7;样板的体积:长度 × 宽度 × 高度=1.5m× 0.3m× 1.2m;建模范围:深度500m (从地表到煤层)、宽度 120m ( 向前煤层)、长度600m ( 横过煤层)。由于煤层较薄,模型多样性结构层的厚度被扩大了5倍。对地表移动和破坏的测量中,14个测微计被放置到模型的顶端。它们中的 7 个(no.1no.7)用于测量垂直移动,而其他

43、(8 号14 号) 要测量水平线移动,如图1。图1模型掘进后的层移动图2数字模型中的地表移动和抑制情况3.3掘进模型的顶端是一个不承载任何负荷的自由表面。在模拟掘进的时候,运行4个掘进头,而且4个层面上的挖掘是同时进行的。一次掘进2厘米,每两次掘进之间间隔2小时。 2组如此操作进行2天,就可以测量掘进造成的明显破坏。在位于上面的煤层完成挖掘之后,继续挖掘比较低的煤层。依照模拟材料模型的记录的变化曲线如图3所示。(a)倾向破坏曲线;(b)沉陷曲线;(c)水平破坏曲线; (d)移动曲线图3模型模拟曲线4.数值分析岩石既有缓冲带也有塑性带,缓冲带受2种力的作用:一是水平压力,另一个是水平张力。实际上

44、,相同的结果的情况下都是考虑压力如何缓解而不考虑张力。 本文只对有效压力作数值分析。此外,在模拟材料模型中做相同的横断面来描绘压力分析,用 2d 有限元的方法 (fem) 能进行充分计算。2d-是对岩石和土壤设计的数值分析系统, 通过它有助于分析对象的力学状态特点。为计算单元,四角形单元比三角形单元具有更大量信息。在煤附近的煤层和岩石层中的单元密度都可以计算。离煤层很远的岩石层的单元身少。有很薄的层按密度划分单位。在 fem 建模中,mohr- 库仑技巧模型沿着横断面建立压力分析,图2数值模型显示沉陷盆地煤层的破坏情况和地层岩石的情况。图4和图5表现出掘进初期的沉陷效果和地表运动的细微变化。破

45、坏程度用2d-模型描绘如图7所示。在所有的掘进步骤完成之后,外力对地层运动的影响如图8所示。煤壁上下压力都集中在此。各种不同的压力不在这里列出,因为有限空间能用fem计算,例如:最大的和最小的压力等图4掘进第一步后模型x轴向的压力图5掘进第一步后模型y轴向的压力图6 所有掘进步骤完成后模型的破坏程度图7第一次掘进后模型所受的剪力图8第一次掘进步骤完成后模型的破坏程度图9所有掘进步骤完成后模型所受的剪力5结论通过建模的实验结果和数值的分析表现出的沉陷曲线和水平移动曲线是不连续和不平滑的, 但在地表引起了一些非对称的变化。获得的沉陷参数,水平面移动参数,顶端沉陷范围和其他的参数在过去一直用于预计地

46、层的运动。(其中沉陷系数是2.0,水平面移动系数是1.22,最大的垂直移动是158mm,凹陷地域的高差45.6m,破碎的地域高差是168m,位于掘进区域的地表移动变形宽度是600m。)这些参数值与当地采矿条件一致,有助于开采作业。实践证明,研究结果也表明在预测地面移动控制和沉陷灾害预计研究中该理论是成功的。 蒂肀羅薀蒁螀膀蒆蒀袂羃莂葿羄膈芈薈蚄羁膃薇螆膇蒂薆罿罿蒈薆肁芅莄薅螁肈芀薄袃芃膆薃羅肆蒅薂蚅芁莁蚁螇肄芇蚀衿芀膃蚀肂肃薁虿螁羅蒇蚈袄膁莃蚇羆羄艿蚆蚆腿膅螅螈羂蒄螄袀膇莀螄羃羀芆螃螂膆节螂袅聿薀螁羇芄蒆螀聿肇莂蝿蝿节芈莆袁肅膄蒅羃芁蒃蒄蚃肃荿蒃袅艿莅蒂羈膂芁蒂肀羅薀蒁螀膀蒆蒀袂羃莂葿羄膈芈薈
