矿山巷道施工中,传统的水平巷道的腰线放样一般有三种方法:用水准仪加钢尺,全站仪或经纬仪加钢尺用伪倾角法来放样和坡度规来放样三种方法。弯道巷道如果坡度变陡,半径变小,传统的放样办法讲无能为力,放样结果只能为近视值。本文作者理论结合实践,苦心钻研,将一个复杂的问题变得简单化,编写程序,所测即所得,超挖,欠挖,腰线高,一两分钟轻松搞定,很好的解决圆曲线巷道的腰线放样难题,及时告知钻工纠偏,保证了工程质量。此放样放方法比北京中国矿业大学大学教科书《矿山测量》的伪倾角法放样办法快,准,值得推广。 In mine roadway construction, there are generally three methods to loft the waist line of traditional horizontal roadway: leveling with a steel gauge, total station or theodolite plus a steel rule with the method of pseudo inclination to set out and the slope gauge to set out three methods. Curved roadway if the gradient steep, the radius becomes smaller, the traditional way to say nothing about lofting, lofting results can only be myopia. The author combines the theory with practice, painstakingly study, to simplify a complex problem, the preparation of the program, the measured income, over-excavation, under-digging, waist high, easy to get a minute or two, a very good solution to circular curve roadway Waist line loft problems, timely informed drilling corrective, to ensure the quality of the project. This method of stakeout is faster, more accurate and worth promoting than the pseudo-dip method of “mine survey”, which is a textbook published by China University of Mining and Technology in Beijing.
