Изобретение относитс к области горной нромышленности и может быть }1спользовано дл определени напр женного состо ни угольного массива в услови х подземной разработки Пластовых месторождений.The invention relates to the field of the mining industry and can be used to determine the stress state of a coal massif under conditions of underground development of the Plastovoe deposits.
Известен способ оценки напр лсенности угольного массива, основанный на проведении базовой скважины, разгрузке и установке в ней датчиков.There is a method of estimating the direction of the coal massif, based on carrying out the base well, unloading and installing sensors in it.
Целью изобретени вл етс создание более точного и 1менее трудоемкого метода определени напр женного состо ни породного массива.The aim of the invention is to create a more accurate and less time-consuming method for determining the stress state of a rock mass.
Это достигаетс тем, что в базовой скважине одновременно определ ют напр жение и температуру массива, при этом устанавливают между ними зависимость, а затем по изменению температуры в других точках массива оценивают напр женное состо ние пород по полученной ранее зависимости.This is achieved by determining the stress and temperature of the array at the same time in the base well, establishing a relationship between them, and then determining the stress state of the rocks from the previously obtained relationship by changing the temperature at other points in the array.
Одним из ранее известных методов определ етс напр жепность массива, окружающего выработки, за цикл посадки основной кровли по всей зоне вли ни очистных работ. Одновременно в соответствующих точках замер ютOne of the previously known methods is determined by the tension of the array surrounding the workings, during the cycle of landing of the main roof throughout the zone of influence of the cleaning works. At the same time, the corresponding points are measured.
температуру массива с номощью терморезисторов и моста сопротивлений. Устанавливают функциональную зависимость между напр женностью массива и его температурой.array temperature with thermistor and bridge resistances. A functional relationship is established between the intensity of the array and its temperature.
Стро т график функцнональной зависимости.Build a graph of functional dependence.
Далее, чтобы определить напр женность точки массива, достаточно замерить ее температуру и по полученной зависимости или ее графику определить соответствующую ей напр женность .Further, in order to determine the intensity of the point of the array, it is sufficient to measure its temperature and, using the obtained dependence or its graph, determine the corresponding intensity.
