Изобретение относитс к определению свойства горных парод вокруг пройденных выработок.The invention relates to the determination of the property of rock species around the excavated workings.
Известны способы визуального определени трещиноватости по количеству или ширине трещин на единицу длины или площади в обнажени х, образцах или скважинах 1.Methods are known for visually determining fracture by the number or width of cracks per unit length or area in outcrops, specimens or wells 1.
Недостатком указанных способов вл етс неизбежна субъективность получаемых данных, плоха их воспроизводимость , невозможность получени объемной пустотности пород в массиве.The disadvantage of these methods is the inevitable subjectivity of the data obtained, their reproducibility is poor, the impossibility of obtaining volumetric voidness of rocks in the massif.
Известен также способ определени трещиноватости горных пород вокруг выработок , включающий бурение шпуров по контуру выработки, поинтервальное нагнетание в шпуры жидкости или газа и проведение измерений до проведени выработкии при удалении от ее контура 2.There is also known a method for determining the fracturing of rocks around workings, including drilling holes along a production contour, interval injection of a liquid or gas into holes, and taking measurements before carrying out development while moving away from its contour 2.
Недостатком указанного способа вл етс неточность определени трещиноватости в зоне вли ни выработки, так как измеренные косвенные реометрические характеристики горных пород позвол ют определ ть только относительную трещиноватость. От распределени трещиноватости завис т, какThe disadvantage of this method is the inaccuracy of determining the fracture in the zone of influence of production, since the measured indirect rheometric characteristics of rocks allow only the relative fracture to be determined. The distribution of fracture depends on how
известно, прочностные и деформационные характеристики горных пород вокруг выработки , величина горного давлени , целесообразность и технологи искусственного укреплени пород тампонажем. Поэтому неточна информаци о трещиноватости привод т , в целом, к неправильным рекомендаци м по способам поддержани горных выработок .it is known, the strength and deformation characteristics of the rocks around the mine, the magnitude of the rock pressure, the expediency and the technology of artificially strengthening the rocks with a tamponage. Therefore, inaccurate information about fracturing leads, in general, to incorrect recommendations on how to support mine workings.
Цель изобретени - повышение точнос ,Q ти способа путем определени распределени коэффициента трещиноватости при удалении от контура выработки. ,The purpose of the invention is to improve the accuracy of the Q method by determining the distribution of the fracture coefficient with distance from the production contour. ,
Поставленна цель достигаетс тем, что дополнительно измер ют смещение пород на контуре выработки, определ ют коэффи15 циент трещиноватости на контуре выработки по формулеThis goal is achieved by additionally measuring the displacement of rocks on the production contour, determining the fracture coefficient on the production contour using the formula
