Abstract
Изобретение относитс к горному делу. Цель изобретени - повышение точности контрол . В кровле горной выработки бур т вертикальные шнуры 1, в которых размещают анкеры 2 со штангами 3, свободные концы которых пропущены через отверсти крепи 4. Смещени пород массива относительно крепи 4 измер ют с помощью датчиков 5, корпусы которых закрепл ют на крепи 4. Дополнительно измер ют смещение крепи 4 относительно опорной реперной точки 6 с помощью сосудов 8 и 9 первого гидростатического нивелира. Положение точки 6 контролируют относительно контрольной реперной точки 7 с помощью сосудов 10 и 11 второго гидростатического нивелира. Рассто ние L2 от шнуров 1 до точки 6 и рассто ние L2 между точками 6 и 7 выбирают из соотношений DΛ1≤2D и L2≤2D, где D - диаметр выработки. Измерение смещений крепи 4 провод т при отсутствии смещений точки 6 относительно точки 7 по сравнению с предыдущим измерением. За абсолютное смещение массива принимают разность величины смещени анкеров 2 относительно крепи 4 и крепи 4 относительно точки 6. 1 ил.The invention relates to mining. The purpose of the invention is to improve the accuracy of control. Vertical cords 1 are placed in the roof of the mine working, in which the anchors 2 are placed with rods 3, the free ends of which are passed through the lining holes 4. Displacements of the mass of the massif relative to the lining 4 are measured by means of sensors 5 whose shells are fixed on the lining 4. Additionally measure the displacement of the support 4 relative to the reference reference point 6 with the help of vessels 8 and 9 of the first hydrostatic level. The position of point 6 is controlled relative to the control reference point 7 by means of vessels 10 and 11 of the second hydrostatic level. The distance L 2 from cords 1 to point 6 and the distance L 2 between points 6 and 7 are chosen from the ratios DΛ 1 ≤2D and L 2 ≤2D, where D is the diameter of the working. The measurement of displacements of the support 4 is carried out in the absence of displacements of point 6 relative to point 7 as compared with the previous measurement. The absolute displacement of the array is taken as the difference between the magnitude of the displacement of the anchors 2 relative to the support 4 and the support 4 relative to the point 6. 1 sludge.
Description
Изобретение относитс к горному делу в частности к методам контрол смещений массива пород и крепи горной выработки, обусловленных про вле- , нием горного давлени .The invention relates to mining, in particular, to methods for controlling displacements of rock mass and lining of mine workings caused by mining pressure.
Цель изобретени - повышение точности контрол ,The purpose of the invention is to improve the accuracy of control,
На чертеже показана схема реализации способа.IQThe drawing shows a diagram of the implementation of the method. IQ
,На схеме обозначены шпуры 1, анкеры 2 со штангами 3, крепь 4 горной выработки, датчики 5 смещени анкеров 2, опорна и контрольна реперные точки 6 и 7 и Сосуды 8, 9 и 10, 11 перво-(5 го и второго соответственно гидростатических нивелиров.The diagram shows holes 1, anchors 2 with rods 3, support for mine workings 4, sensors 5 for displacement of anchors 2, reference and reference fixed points 6 and 7 and vessels 8, 9 and 10, 11 first and second levels.
Способ осуществл етс следующим образом .The method is carried out as follows.
В кровле горной выработки бур т 20 вертикальные шпуры 1. В шпурах 1 ус- та авливают анкеры 2 со штангами 3, свободные концы которых пропущены в выработку через отверсти в крепи 4.In the roof of mine workings there are 20 vertical holes 1. In the holes 1, anchors 2 with rods 3 are inserted, the free ends of which are passed into the production through holes in the supports 4.
сосудов 8 и 9 первого гидростатического нивелира. Стабильность положени опорной реперной точки 6 контролируют , сравнива разности показаний на шкалах сосудов 10 и 11, котора должна быть одинаковой перед началом каждой серии измерений и в конце ее.vessels 8 and 9 of the first hydrostatic level. The stability of the position of the reference reference point 6 is controlled by comparing the difference of indications on the scales of vessels 10 and 11, which should be the same before the beginning of each series of measurements and at the end of it.
В случае несовпадени разности показаний водомерных сосудов 10 и 11 с разностью предыдущего замера удал ют от зоны вли ни реперные точки 6 и 7 до совпадени отсчетов, т.е. до отсутстви смещений опорной точки 6 относительно контрольной точки 7,If the difference between the readings of the pressure vessels 10 and 11 does not match the difference of the previous measurement, the reference points 6 and 7 are removed from the zone of influence until the readings coincide, i.e. until there are no shifts of the reference point 6 relative to the reference point 7,
