Description

Изобретение относитс  .к способам креплени  капитальных и подготовительных горных выработок анкерной крепью в сочетании с основной рамной крепью. Известен способ креплени  проводимых горных выработок, при котором в пространстве между забоем и основной рамной крепью устанавливают временную анкерную крепь в чистом виде или в комбинации с верхним элементом рамной крепи 1 . Недостаток .такого способа заключаетс  в том, что при нормированном отстава нии посто нной рамной крепи от забо  не 1 более, чем на 3 м она подверЖШа повреж дени м при ведении взрывных работ. Известен также способ креплени  проводимых тюрных выработок, включахшшй устаиовку вслед за подвиганием забо  анкеров и возведени  на рассто нии от за бо  основной рамной крепи 2 . Однако при этом величина безопасного отставани  рамной крепи в случае ттроведенв  выработки буровзрывным способом не определена. Цель изобретени  - предотвращение повреждений рамной крепи при проведении выработок буровзрывным способом. Поставленна  цель достигаетс  тем, что рамную крепь возвод т с отставанием от забо  не менее 25-5 О м. На чертеже изображена призабойна  часть проводимой выработки, продольный разрез. Способ осуществл етс  следующим образом . Кровлю (при необходимости и бока) проводимой капитальной или подготовительной выработки вслед за подвиганием забо  креп т анкерами 1 под опорные элементы , которыми могут быть в зависимости от горно-геологических условий ме талпические шайбы, верхн ки, р иетчата  зат жка, металлическа  сетка и др. Затем с отставанием от забо  выработки на 255О м специализированна  бригада срепиль шиков в дополнение к установленной анкерной крепи возвод т основную рамную жоепь Г21 .The invention relates to methods for fastening capital and preparatory mine workings with anchor bolts in combination with main frame braces. There is a known method of fastening the conducted mine workings, in which temporary anchoring lining is installed in the space between the face and the main frame lining in pure form or in combination with the upper element of the frame lining 1. The disadvantage of this method lies in the fact that with the normalized lagging of the permanent frame support from the bottom one by more than 3 meters, it will subject it to damage during blasting operations. There is also known a method of fastening ongoing tunnel workings, including installation, following the advancement of the anchor and the erection of main frame support 2 away from behind the bo. However, the magnitude of the safe lag of the frame support in the case of ttrodens in the development of drilling and blasting method is not defined. The purpose of the invention is to prevent damage to the frame lining during workings by drilling and blasting. The goal is achieved by the fact that the frame support is erected with a gap of not less than 25-5 O m. The drawing shows the bottom part of the development, a longitudinal section. The method is carried out as follows. Roofing (if necessary, and the side) of the capital or preparatory development being carried out following the advancement of the bottom was secured with anchors 1 under the supporting elements, which, depending on the geological conditions, could be metallic washers, tops, gripping, metal mesh, etc. Then, with a delay of 255 m from the development of the mine, a specialized team of fasteners of chicles, in addition to the installed roof bolts, erected the main frame joist G21.

Указанны параметр отставани  воэвеаени  основной рамной крепи установлен на данных шахтных эксперементов, результаты которых приведены ниже:The specified lagging parameter of the main frame support is installed on the data of mining experiments, the results of which are given below:
