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(bào)告河南龍潤煤業(yè)有限公司井上下控制測量報(bào)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(biāo)系統(tǒng)和高程系統(tǒng)首先進(jìn)行了聯(lián)系測量。地面已知點(diǎn)采用礦方提供1980西安坐標(biāo)系統(tǒng)測量數(shù)據(jù)：點(diǎn)名X坐標(biāo)（米）Y坐標(biāo)（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(diǎn)

2、的精度，兩個(gè)已知點(diǎn)的水平邊長為70.168m用全站儀檢測已知點(diǎn)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(diǎn)的精度不超過7cm因此兩個(gè)已知點(diǎn)可以作為聯(lián)系測量的近井點(diǎn)。根據(jù)礦方需要又在風(fēng)井附近建立兩個(gè)近井點(diǎn)，按15秒導(dǎo)線點(diǎn)進(jìn)行連測，連測結(jié)果如下：點(diǎn)名X坐標(biāo)（米）Y坐標(biāo)（米）坐標(biāo)（米）近井點(diǎn)13772739.77238423368.686319.184風(fēng)井頂3772812.69638423347.900318.53
