煤矿巷贯通误差预计

-850西大巷与八采区下部石门贯通误差预计工程概况xxx矿业公司-850西大巷与八采区下部石门的对向贯通工程主要包括两大部分：一部分：-850西大巷（由-850水平井底车场至八采区下部石门开口处部分）总工程量4475.490m。该工程于2004年5月27日开工，至2006年2月施工约1360米，约剩3100m即到八采区下部石门开口点K处。-850西大巷设计参数（井底车场~八采段）：第一段α方位=225°，长60m,I=+3‰第二段α方位=196°，长1100.002m，I=+3‰α方位=219°，长2167.541m，I=+3‰第四段α方位=214°，长582.35m，I=+3‰第五段α方位=220°，长565.597m，I=+3‰另一部分：经由-600水平八采区施工的八采轨道山经轨道山下部车场向前延伸到八采区下部石门口，总工程量=SUM(ABOVE)1047.574m。2004年7月30日，该项工程施工至轨道山下部车场曲终13.6m处，剩46m即到八采区下部石门与轨道山巷交点处。-850西大巷、八采区轨道山及八采区下部石门均采用全断面掘进，一次成巷，工程完工后，可以确保xxx矿业公司生产衔接。根据[煤矿测量规程]规定以及接合工程需要，规定贯通在水平重要方向上的允许偏差为±0.3m，高程方向上的允许偏差±0.2m。2、贯通测量方案选择2.1导线布设导线一端：由-600水平中石门ⅢZ-02~ⅢE-02导线边起始经-600东大巷、-600~-850串车下山到达-850水平井底车场Ⅳ-05，然后沿-850西大巷布设导线至ⅣW-27~K。导线另一端：由ⅢE-02~ⅢZ-02导线边起始经-600西大巷到达八采轨山开口处ⅢW-37，再沿八采轨道山施测到八采区下部石门巷交~K。贯通导线全长12166.75m。为了提高导线精度，未来拟布设的导线边长大部分控制在140~180m左右，两端导线到达K点后，形成闭合环。目前，为保障工程施工，导线一端已由ⅢE-02点施测至-850水平ⅣW-05点，独立观测两次，共22站，长2723.75m。另一端由ⅢE-02点经-600西大巷和八采轨道山测至Ⅷ-08点，分10个阶段测量，全长5609m，共计47站。水平角观测及限差选用瑞士产WILDT2经纬仪（2004年以前）或SOKKIA全站仪观测水平角，以测回法进行观测。导线边长大于20m时，每站采用两次对中两测回，测回间变换度盘位置，导线边长小于20m时，采用两次对中四个测回，测回间变换度盘位置。在风速较大的地段，为保证观测精度每测站对中时采用挡风布挡风，前后视加大垂球重量。限差要求：同一测回半测回互差小于12″，一次对中测回间互差小于10″，两次对中测回间互差小于15″。导线边长丈量限差要求采用REDmini2光电测距仪（2004年以前）和SOKKIA全站仪测边时，每条边采用往返测，其偏差：一测回内读数较差不大于3mm，往返观测同一条边时，化算到水平距离后（经过改正）互差不大于1/8000。取两次量边平均值做最终值。水准测量采用S3型水准仪往返观测，每站采用两次仪器高观测（两次变换仪器高度要超过10cm），测得高差互差不大于5mm。往返水准测量限差：小于50mm（R为线路长，单位km）。取往返观测平均值做为最终值。三角高程测量采用三角高程测量法进行倾斜巷道高程观测。每站丈量仪器高和觇标高各两次，互差不大于4mm，取平均值为最终结果；相邻两点往返测得高差互差不大于10mm+0.3（为导线水平边长，单位m）；三角高程闭合差不大于100mm。控制导线延长随巷道延伸，采用激光指向仪标定方向线，平均每70m向前延伸一次±30″导线，巷道每300~500m延测一次±5″导线，依据实测结果，反推巷道方位及坡度，及时调整巷道中腰线。3.在不加测陀螺定向边情况下，贯通点K误差预计依据工程施工现状，选取贯通点为K处。根据多年获取的大型贯通经验，只对水平重要方向（x/轴方向）进行贯通误差预计。建立以K点为原点，以α=310。为x/轴，以α=220。为y/轴的预计坐标系，各导线边假定方位角αi/=αi+50。。3.1误差参数确定测角中误差：虽然对已经取得的部分观测成果进行分析后得出WILDT2经纬仪测角中误差约为±4.4″和SOKKIA全站仪的测角中误差约为±4.6″，但因已经实测的导线为10多批次且线路途径许多恶劣环境地段，故放宽mβ=±5″。导线边长丈量相对中误差：基于同样理由，导线边长相对中误差放宽至1/8000。井下水准单位长度高差中误差：井下水准测量允许闭合差为50mm，所以往返测量的单位长度中误差为Mh水准=井下三角高程单位长度中误差：井下三角高程测量允许闭合差为100（mm）。所以独立两次测量中误差为Mh三角=±（mm）=±35.4（mm）3.2未加测陀螺定向边时，贯通相遇点K水平重要方向误差（计算见表-1）①由经纬仪导线测角引起水平重要方向误差Mxβ=式中mβ=±5〃Ryi：贯通相遇点K与各导线点连线在Y轴上投影长度，其值计算见表-1。②由光电测距仪量边引起水平重要方向误差。Mxl=式中=1/8000，为各条导线边在X/-O-Y/坐标系内假定方位角。为相邻两点的导线点的边长独立两次测量，上述两项误差引起贯通相遇点K水平重要方向中误差。Mxk=贯通相遇点K在水平重要方向上的预计误差Mxk预=2Mxk=±1.002m由此预计误差可以看出，Mxk预太大，如不采取特殊手段，贯通精度远不能满足工程需要。在未加测陀螺定定向边情况况下贯通点点K的误差预预计点位X坐标Y坐标边长Lα方位(弧度）α方位（度数）α＇方位（弧度）RiRyi*RyiiL*L*COSSα＇*COSSα＇ⅢZ-02384683..287743.77570.7915996816645.35511949661.66426614301.7668183440225.5660ⅢZ-04384619..587810.558892.3230.8130119368846.58266177771.68568834305.5996182945442.4112.008811ⅢW-01384587..887816.66532.3620.8193775614446.94688041551.6920444288.2337181199778.45515.3199910944ⅢW-02384499..187907.117126.70330.8488445911148.63533292221.7215114295.7224180372449.866361.8988838ⅢW-03384462..187915.229437.870.8565990901149.07900848771.72925554277.5006178414665.81135.7094480466ⅢW-04384394..687912.338367.5940.8681999874449.74422305991.74086644231.3557173915111.033130.878827377ⅢW-05384336..987915.004757.7360.8790999304450.36877224221.75176634196.377170390994.966107.980052244ⅢW-06384282..887880.22164.3470.8838002031150.63811690881.75646664135.0777165161555.399141.104484511ⅢW-07384185..387799.7752126.38660.8898667738850.98577087771.76253324011.1229155048991.299580.060097644ⅢW-08384114..387744.335290.0910.8950448462251.28255426661.76771123923.4113148039556.699310.673354255ⅢW-0938397687636.66175.32440.9058443459951.90100509221.77850073753.0552134863992.2551307.21152322ⅢW-10383865..387550.0005140.50660.9151445694452.43400301991.7878113616.799124747228.2915.237763111ⅢW-11383827..987525.99644.5410.9193558195552.67533889111.79202223574.9004121646116.29995.5201106899ⅢW-12383718..487544.7759111.00550.9472776554.27499913441.8199443524.8993116694552.477749.172201444ⅢW-13383597..787454.1146150.97220.9606222676655.03966715111.83328873381.1224106622445.6551534.69935244ⅢW-1438349187367.5587137.40220.9722772993355.70711860881.84493373249.26697839244.43111383.64485155ⅢW-15383383..387283.5515136.60.9856002953356.470993721.85826673119.411989485377.93661500.00012544ⅢW-16383287..487207.9917122.140.9983225157757.19988664111.87098893003.655482330499.27111304.466115ⅢW-17383202..187145.4475105.68661.0113552727757.946229181.88401172905.222476389988.45111060.43385866ⅢW-18383080..787046.6632156.59111.0296660532258.99522526551.90232242757.455567980155.18222597.79917666ⅢW-19382979..786967.8806128.11.0470776156659.99300952441.9197442638.277761468288.75441918.27716722ⅢW-20382823..986849.4453195.691.0778992363361.75877353111.95055562459.011752158400.12885262.31121066ⅢW-21382705..886753.3397152.16111.1031222173363.20422981881.97578862319.299445440499.57663594.34445855ⅢW-22382573..586631.2237180.10661.1324337173364.88399253662.00510012151.511338094166.09115743.36607455ⅢW-2338249486554.7778110.2944198911737772.02439912048.922433919766.79222335.86667733ⅢW-24382417..286485.1127103.70441.1731337164467.21588650442.04580011954.488430210077.18112249.444005ⅢW-25382300..386377.6655158.77221.2096554006669.30811277662.08231181811.344724948077.47556040.344053
