Description
Изобретение относитс к горной промышленности и предназначено дл защиты подрабатываемых объектов.The invention relates to the mining industry and is intended to protect the objects being worked up.
Целью изобретени вл етс повышение эффективности защиты подрабатываемых объектов при разработке крутопадающих пластов, имеющих выход на поверхность весьма тонких наклонных пластов угл в пределах защитной зоны объекта за счет уменьшени деформации земной поверхности.The aim of the invention is to increase the efficiency of protection of undermined objects in the development of steeply dipping seams having access to the surface of very thin inclined coal seams within the protective zone of the object by reducing the deformation of the earth's surface.
Способ осуществл етс следующим образом .The method is carried out as follows.
Дл защиты охран емого объекта по данным геологоразведочных работ, проведенных в этом районе, подбирают тонкие пласты мощностью от 0,4 м и менее, содержащиес в них вредные примеси не учитываютс . Запасы полезного ископаемого таких пластов обычно не включаютс в промыщ- ленные запасы шахты. Указанные тонкиеIn order to protect the protected object, according to the data of geological exploration carried out in this area, thin layers with a thickness of 0.4 m and less are selected; harmful impurities contained in them are not taken into account. Mineral reserves of such reservoirs are usually not included in the industrial reserves of the mine. Mentioned thin
пласты подбирают таким образом, чтобы выходы их на земную поверхность находились перед и за охран емым объектом. При этом рассто ние от объекта до вы- хода пласта под наносы равно не менее щирины бермы безопасности. Затем выполн ют расчет веро тных деформаций от выбранных пластов, примен упрощенную методику расчета без учета календарного плана горных работ. Производ т газификацию пластов до проектной глубины. В результате газификации пластов создаетс зона разрыва сплошности пород в массиве. Зона разрыва представл ет выдержанную под одним углом наклонную плоскость, в которой сцепление пород в направлении перпендикул рном плоскости отсутствует. Така зона разрыва сплошности пород гасит деформации в охран емом объекте при отработке целиков.The layers are selected so that their exits to the earth's surface are in front of and behind the protected object. In this case, the distance from the object to the formation of the bed under sediments is no less than the width of the safety berm. Then, the calculation of probable deformations from the selected strata is performed using a simplified method of calculation without taking into account the mining schedule. Produce gasification to the design depth. As a result of gasification of the layers, a zone of discontinuity of rocks in the massif is created. The fracture zone is an inclined plane sustained at one angle, in which there is no adhesion of rocks in the direction perpendicular to the plane. Such a zone of discontinuity of rocks suppresses deformations in a protected object during the development of pillars.
