【摘要】 在煤矿井下水准测量中,水准网常布设为沿巷道的长条型或方格网型,这些水准网中经常含有多个闭合环。然而,由于测量过程中各种误差影响,其闭合环存在一定高差闭合差。通常采用条件平差或间接平差法以消除高差闭合差。但是因其计算的复杂性,所以在实际井下作业时经常带来不可避免的麻烦,尤其是复杂的井下测量水准网。为了进一步提高和优化井下水准测量成果的精度,方便、有效、快捷地完成井下测量作业,采用了逐环分配闭合差的方法对其进行数据处理。通过理论分析及实例计算验证分析,结果表明,相比较条件平差法,逐环分配闭合差法是一种更简便、实用和行之有效的水准网数据处理方法。更多还原

【Abstract】 In the leveling measurement of coal mine,the leveling network often layout as strip or grid along the tunnel,which often include many closed loops.However,due to the influence of various errors in the measurement process,there are some closure errors in the closed loop.Usually the conditional adjustment and parameter adjustment are used to adjust the height closure errors.Nevertheless,because of its complexity,it often brings unavoidable trouble in actual underground working,especially the complex leveling network.In order to further improve and optimize the accuracy of the underground measurement results,completing the coal underground measurement conveniently,effectively and quickly,the method of loop by loop adjustment is putted out.The results of theoretical analysis and example calculation show that compared with the conditional adjustment method,the method of loop by loop adjusting closure errors is simple,practical and effective data processing method for leveling network.更多还原
