Embodiment Construction

[0020] Below in conjunction with accompanying drawing to the embodiment of the underground long-distance roadway waistline calibration method described in the present invention (taking Shanxi Province Jincheng Coal Industry Group Co., Ltd. Sihe Coal Mine's Dongsi Pan District Concentrated Transport Lane 27 # —42 # Take the waistline calibration method of Hengchuan roadway as an example) to describe in detail.

[0021] A survey team consisting of 5 people surveyed Dongsi District Transportation Lane 27 # —42 # The waistline of Hengchuan roadway is calibrated, and the instruments and tools used are: total station with laser pointer, semicircular instrument, tripod, benchmark, 5-meter tape measure, and red paint. On-site recorded data include: location, time, staff, recorder, measurer, station elevation and point number of each measuring point, instrument height, horizontal distance; requirements: to measure the height of the bottom and top of the roadway, and use the measur...

Abstract

The invention relates to the field of mine survey, in particular to a calibration method for a waist line of a underground long-distance tunnel, and solves the problem that two waist lines of the tunnel have an accumulated error in the existing calibration method for the waist line of the long underground tunnel of the mine. The calibration method for the waist line of the underground long-distance tunnel of the mine comprises the following steps of: (1) accurately measuring a top plate and a bottom plate of the existing tunnel, drawing a cross-section design chart of the tunnel, marking cross sections at each point of gradient change of the tunnel in the design chart by A, B, C, D... until a cross section at the end of the tunnel, and designing a bottoming slope and a horizontal distance for each section of the tunnel, and bottoming thickness of each of the cross sections of the tunnel; and (2) calibrating points of the two waist lines of the tunnel on site. The calibration method for the waist line of the underground long-distance tunnel disclosed by the invention plays an important role in a bottoming process of the underground tunnel and a tunneling process of a stone drift, therefore, accuracy of breakthrough in a counter-tunneling process or a reverse-tunneling breakthrough process of the stone drift is increased, an effective guarantee is provided for breakthrough of the tunnel and enormous economic benefits are created.

Description

technical field [0001] The invention relates to the field of mine surveying, in particular to a calibration method for long-distance roadway waistlines in underground mines. Background technique [0002] The calibration of the waistline is one of the main tasks of underground roadway construction measurement. The waistline is usually marked on the two sides of the roadway to control the slope of the roadway. The measuring point for calibrating the waistline of the roadway is called the waistline point, and the straight line formed by several waistline points is the waistline of the roadway. [0003] Accurate calibration of the waistline of the long-distance underground roadway is the pre-procedure work for the hardening of the floor of the long-distance roadway. Construction, if the calibration of the roadway waistline is inaccurate, it will greatly increase the engineering volume of the roadway bottom construction, and waste a lot of manpower, material resources and financ...
