Description
Изобретение относитс к промьшшен . ности строительньзх материалов и може использоватьс при добыче каменных блоков в подземных услови х. Известны способы добычи каменных блоков в подземных услови х, использующие бурение шпуров в кровле выработки дл установки анкерного креплени 1 . Недостатком их вл етс низка производительность добычи каменных блоков из-за неодновременности бурени шпуров в кровле выработки и резки вертикальных пропилов по длине забо . Известны также способы добычи каменных блоков, включающие бурение, р да шпуров в кровле выработки дл установки анкерного креплени и резку вертиксшьных пропилов по длине забо 2. Недостатком этих способов вл етс низка производительность добычи каменных блоков, Цель изобретени - увеличение про изводительности добычи каменных блоков Это достигаетс тем,что резка вер цикальных пропилов и бурение р да ип ров в кровле выработки дл установки анкерного креплени производитс одновременно, причем шаг расположени шпуров в р ду кратен ширине вырезаемого блока, а рассто ние между р дами шпуров кратно длине блока. На чертеже изображено расположение р да umypoB в кровле выработки и вертикальных пропилов. Способ добычи каменных блоков заключаетс в том, что бурение шпуров 1 производитс в процессе резки вертикальных пропилов 2 кг нерезной машиной путем сверлени пород кровли 3 буровым инструментом, устанавливаемым в шпиндель бурового устройства, закрепл емого на каретке, подающей режущий инструмент камнерезной машины. Перед резкой очередного вертикального пропила при нижнем положении каретки камнерезной машины в буровое устройство закрепл етс бурова штанга . Затем одновременно включаетс привод вращени штанги и инструмента дл вертикальной резки пропила. Подача каретки синструментами осуществл етс до крайнего верхнего положени . По окончании этих операций осуществл етс подача каретки до крайнего нижнего положени и сн ти буровой штанги. Затем производ тс операцииThis invention relates to industrial. construction materials and can be used in the extraction of stone blocks in underground conditions. Methods are known for the extraction of stone blocks in underground conditions, using the drilling of bore holes in the roof of the mine for anchor installation 1. Their disadvantage is the low productivity of extraction of stone blocks due to the non-simultaneity of drilling holes in the roof of the production and cutting of vertical cuts along the length of the bottom. There are also known methods for extracting stone blocks, including drilling, a series of holes in the roof of the mine for installing anchor and cutting vertical cuts along the length of the slab 2. The disadvantage of these methods is the low productivity of stone blocks mining, This is achieved by cutting vertical cuts and drilling a number of types in the roof of the mine for anchoring at the same time, with the step of drilling holes in the row the width of the block to be cut, and the distance between the rows of drill holes is a multiple of the block length. The drawing shows the location of a row of umypoB in the roof of the excavation and vertical cuts. The method of extracting stone blocks is that drilling holes 1 is made in the process of cutting vertical cuts 2 kg with an uncut machine by drilling roof rocks 3 with a drilling tool installed in the spindle of the drilling device mounted on the carriage feeding the cutting tool of the stone cutting machine. Before cutting the next vertical cut at the lower position of the carriage of the stone-cutting machine, a drill rod is fixed in the drilling device. Then, the rotational drive of the rod and the tool for vertical cutting of the kerf are simultaneously turned on. The carriage of the carriage by the instruments is carried out to the extreme upper position. At the end of these operations, the carriage is delivered to the lowest position and the drill rod is removed. Then operations are performed.
