Description
II
Изобретение относитс к технике проведени подготовительных выработок буровзрьюным способом и может быть использовано в угольной и горнорудной отрасл х промышленности.The invention relates to a technique for carrying out preparatory workings using drilling and drilling method and can be used in the coal and mining industries.
Известны устройства цл снижени разлета кусков горной массы при буровзрьтных работах. К таким устройствам относ тс оградительные щиты l.Devices are known for reducing the dispersion of pieces of rock mass during drilling and drilling. Such devices include protective shields l.
Недостатком этих устройств вл етс низка стойкость к воздействию значительных ударных нагрузок, т. е. сам щит представл ет из себ жесткую кон струкцию с низкой амортизирующей способностью .The disadvantage of these devices is their low resistance to the effects of significant shock loads, i.e. the shield itself is a rigid structure with a low damping capacity.
Наиболее близким по технической сущности и дocтиJ aeмoмy результату вл етс устройство дл ограничени разлёта взорванной массы при проведении выработок, включающее сетчатую металлическую перемычку, перекрывающую все сечение вьфаботки и закрепл емую к верхн ку и стойкам креплени вьфаботки с помощью троса, при этом сетчата пе-The closest in technical essence and accessibility is the device for limiting the spread of the blasted mass during the mine workings, including a mesh metal jumper that covers the entire cross section of the refractory and is fixed to the top and racks of the fastening of the refractory with a cable, while
ремычка состоггт из двух частей, а нижн часть снабжена разъемным щвелле- ром. обеспечивающим независимое подн тие частей сетчатой перемычки РЗНецостаток устройства - недостаточна стойкость перемычки к воздействию значительных ударных нагрузок, так как она жестко св зана с конструкцией крепи вьфаботки, при этом воспринимаема The strap is composed of two parts, and the lower part is equipped with a split channel. providing independent lifting of the parts of the net bridge of the device, the device’s restraint is insufficient resistance of the bridge to the impact of significant shock loads, as it is rigidly connected with the lining design, while it is perceived
0 ею акнамическа нагрузка передаетс на элементы креплени вьфаботки, которые имеют ограниченный запас прочности .By this, an acnemic load is transmitted to the fastener fastening elements, which have a limited margin of safety.
Кроме того, конструкци рассматри5 ваемой перемычки предусматривает перекрытие всего сеченк проводимой выработки , Б результате чего затрудн етс доступ людей в забой до и после взрывных работ.In addition, the design of the jumper under consideration provides for the overlapping of the entire sechenk of the development to be carried out, resulting in difficult access for people to the face before and after blasting.
Цель изобретени - повьшюние надежности работы и обеспечение возможностисвободного поступа людей к забою.The purpose of the invention is to increase the reliability of work and to ensure the possibility of free movement of people to the face.
