河南龍潤煤業(yè)有限公司井上下控制測量總結(jié)

1、河南龍潤煤業(yè)有限公司井上下控制測量報告河南龍潤煤業(yè)有限公司井上下控制測量報告一、測量概述：測量概述：為了在河南龍潤煤業(yè)有限公司建立統(tǒng)一的坐標系統(tǒng)和高程系統(tǒng)首先進行了聯(lián)系測量。地面已知點采用礦方提供1980西安坐標系統(tǒng)測量數(shù)據(jù)：點名X坐標（米）Y坐標（米）高程（米）辦公樓頂3772766.65338423696.595350.444變電所3772712.44738423741.151349.040在聯(lián)系測量前，首先檢查了井口附近地面已知點

2、的精度，兩個已知點的水平邊長為70.168m用全站儀檢測已知點邊長為70.156m，差值為1.2cm，煤礦測量規(guī)程第50條規(guī)定：近井點的精度不超過7cm因此兩個已知點可以作為聯(lián)系測量的近井點。根據(jù)礦方需要又在風井附近建立兩個近井點，按15秒導線點進行連測，連測結(jié)果如下：點名X坐標（米）Y坐標（米）坐標（米）近井點13772739.77238423368.686319.184風井頂3772812.69638423347.900318.53
