Description
(54) СПОСОБ СОЗДАНИЯ ЛЕДЯНОЙ ИЗОЛЯЦИОННОЙ ПЕРЕМЫЧКИ И ЕЕ ЛИКВИДАЦИИ(54) METHOD OF CREATING AN ICE INSULATING BAND AND ITS ELIMINATION
Изобретение относитс к горному делу и может быть использовано при изол ции горных выработок, преимущественно в шахтах с отрицательной температурой, а также дл возведени взрывоустойчивых перемычек при изол ции подземных пожаров.The invention relates to mining and can be used to isolate mine workings, mainly in mines with a negative temperature, as well as to erect blast-proof bridges when isolating underground fires.
Известен способ возведени гипсовой взрьгеоустойчивой перемьмки, заключающийс в установке опалубки в горной выработке и подаче на опалубку гипсового раствора 1}.There is a method of erecting a gypsum, vortex-resistant pemrychki, which consists in installing the formwork in the mine workings and applying to the formwork gypsum solution 1}.
Недостатком зтого способа вл етс больша трудоемкость доставки материалов и возведени перемычки.The disadvantage of this method is the great complexity of the delivery of materials and the construction of lintels.
Известен способ создани лед ной изол ционной перемычки и ее ликвидации, заключающийс в предварительной установке в сечении горной выработки породоспуска с гидравлической разгрузкой трубчатого теплообменника, выполненного в виде спирального трубопровода , содержащего по меньщей мере один виток трубопровода, который размещают по периметру поперечного сечени ствола породоспуска над гидравлическим узлом разгрузки и соединенного со средствами подачи хладоагента иThere is a method of creating an ice insulating jumper and its elimination, which consists in the preliminary installation in a cross section of a mine working with a hydraulic discharge of a tubular heat exchanger made in the form of a spiral pipe containing at least one turn of the pipeline that is placed around the perimeter of the cross section of the rock landing over hydraulic unloading unit and connected to the means of supplying refrigerant and
теплоносител с холодильным и нагревательным аппаратами, подача хладоагента, в качестве которого используют раствор хлористого кальци дл замораживани воды, подаваемой на поверхность трубчатого теплообменника дл образовани лед ной перемычки (лед ной пробки), и последующей подаче теплоносител в теплообменник дл ликвидации намороженного льда 2.coolant with refrigeration and heating devices, coolant supply, which is used as a calcium chloride solution for freezing water supplied to the surface of the tubular heat exchanger to form an ice bridge (ice block), and then feeding the coolant to the heat exchanger to eliminate frozen ice 2.
10ten
Недостатками данного способа вл 19тс длительное врем создани перемычки вследствие размещени трубчатого теплообменника по периметру выработки и невозможность его использовани дл возведени взрьтоустой 5 чивых перемычек при изол ции подземных пожаров и уменьшени времени на ликвидацию аварии, а также отсутствие контрол за поддержанием отрицательной температуры перемычки .The disadvantages of this method are the long time to create a jumper due to the placement of a tubular heat exchanger around the perimeter of production and the impossibility of using it to erect a sparse 5 bridges while isolating underground fires and reducing the time to eliminate the accident, and the lack of control over maintaining the negative jumper temperature.
