摘要
为保障木瓜煤矿10-201工作面的顺利贯通,根据贯通测量技术,采用15″级采区控制导线测量标准,结合工作面的特征和测量标准,进行井下导线和高程的测量作业,基于贯通测量结果得出15″级采区经纬仪闭附检核成果表。工作面掘进贯通后,通过精度评定分析得出,工作面贯通闭合计算验证中线方向左右偏差为0.033 m,小于容许偏差±0.3 m,保障了工作面的顺利掘进贯通。
In order to ensure the smooth mining of 10-201 working face in Mugua Mine,according to the penetration measurement technology,15″level mining area control conductor measurement standard was adopted,combined with the characteristics of the working face and measurement standard,underground conductor and elevation measurement operation was carried out,based on the results of penetration measurement to derive 15″level mining area latitude and longitude instrument closure check results table.The accuracy evaluation analysis showed that the deviation of the left and right of the centerline direction was 0.033 m,which was less than the allowable deviation of±0.3 m,which ensured the smooth mining of the workface.
