Description
Изобретение относитс к горной, промышленности, в частности к способам определени глубины оттаивани мерзлых пород и грунтов.The invention relates to the mining industry, in particular, to methods for determining the depth of thawing of frozen rocks and soils.
Известен способ определени глубины оттаивани горных пород, включающий бурение шпуров из выработок в исследуемом массиве и определение в них температуры с помощью температурных датчиков 1.There is a known method for determining the depth of thawing of rocks, which includes drilling holes from workings in the array under study and determining the temperature in them using temperature sensors 1.
Известен также способ определени глубины оттаивани горных пород, включающий бурение шпуров 2 .There is also known a method for determining the depth of thawing of rocks, including drilling holes 2.
Однако эти способы отличаютс большой сложностью. Необходима установка большого количества термометров или температурных датчиков, а также измерительной аппаратуры, возникает необходимость предварительной дегазации угольных и рудных пластов., опасных по выбросам, так как аппаратура выполнена в невзрывобезопасном состо нии.However, these methods are very complex. It is necessary to install a large number of thermometers or temperature sensors, as well as measuring equipment, there is a need for preliminary degassing of coal and ore formations that are dangerous for emissions, as the equipment is made in a non-explosion-proof state.
Цель изобретени - упрощение процесса измерений и непосредственное определение границы отта вших вечномерзлых пород.The purpose of the invention is to simplify the measurement process and directly determine the boundary of frozen permafrost.
Эта цель достигаетс тем, что согласно способу в шпур помещают .влажный снег, а затем измер ют частьThis goal is achieved in that, according to the method, wet snow is placed in the hole, and then a part of
шпура, освободившуюс от снега в процессе его оттаивани , по величине которой определ ют глубину оттаивани горных пород.the hole that was cleared from the snow during its thawing process, and the depth of thawing of rocks is determined by the amount of snow.
На фиг. 1 и 2 показано расроложение шпуров в горной выработке; на фиг. 3 - устройство дл реализации предлагаемого способа.FIG. 1 and 2 show the divergence of bore holes in the mine workings; in fig. 3 - a device for implementing the proposed method.

Способ заключаетс в том, что S горной выработке 1 бур тс шпуры 2 на глубину 1, 5 и 2 м. Затем в про- бурённый шпур 2 помещают влажный снег 3 с последующей утрамбовкой The method consists in the fact that S to the excavation 1 of the drill of hole 2 to a depth of 1, 5 and 2 m. Then wet snow 3 is placed into the drilled hole 2 followed by ramming
15 ( уплотнением). Шпур заполн етс снегом с оставлением свободной части шпура уусть дл пробки 4.Пробка 4 изготовл етс из различного материала , например дерева, конической фор20 мы и имеет с одной стороны срез на всю ее длину дл стока воды. Заполнение шпуров 2 снегом 3 производитс с помощью устройства, состо щего из трубы 5, имеющей диаметр, 15 (compaction). The hole is filled with snow, leaving a free part of the hole for the cork 4. Cork 4 is made of various materials, for example wood, a conical shape and we have on one side a cut to its entire length for water flow. Filling the bore holes 2 with snow 3 is performed using a device consisting of a pipe 5 having a diameter
25 равный диаметру шпура, в которую :. вставл етс забойник 6. Сначала снег помещаетс в трубу 5, затем труба приставл етс к устью шпура 2 и злбойником б снег проталкиваетс в 25 equal to the diameter of the hole, in which:. a rammer 6 is inserted. First, the snow is placed in pipe 5, then the pipe is attached to the mouth of bore-hole 2 and the snow is pushed forward
30 шпур 2.30 hole 2.
