Description

Изобретение относится к горной промышленности и может быть использовано для определения выбросоопасных зон в массиве соляных пород.The invention relates to the mining industry and can be used to determine outburst zones in an array of salt rocks.

Цель изобретения — повышение точности определения выбросоопасных структур путем выявления ядра выбросоопасной структуры.The purpose of the invention is to improve the accuracy of determination of outburst structures by identifying the core outburst structures.

На фиг. 1 представлен план лавы с изображением точек замера температуры; на фиг. 2 — график распределения температуры по длине лавы; на фиг. 3 — схема расположения шпуров, оконтуривающих ядро выбросоопасной зоны.FIG. 1 shows the plan of the lava with the image of the temperature measurement points; in fig. 2 is a graph of temperature distribution along the length of the lava; in fig. 3 - the arrangement of holes, contouring the core of the outburst zone.

Способ осуществляется следующим образом.The method is as follows.

Перед началом ведения горных работ в лаве определяют наличие гологических нарушений, при их обнаружении приступают к оценке их выбросоопасности.Before starting mining operations in the lava, the presence of gologic disturbances is determined, and if they are detected, they begin to assess their outburst risk.

В условиях лавы, начиная от вентиляционного штрека, в сторону геологического нарушения через каждые 3 м определяют температуру поверхности соляных пород на груди забоя по всей его длине.In terms of lava, starting from the ventilation drift, the temperature of the surface of salt rocks on the bottom of the chest along its entire length is determined every 3 m to the side of the geological disturbance.

Результаты полученных данных наносят 5 на график (фиг. 2), по которому устанавливают зону пониженных температур, что свидетельствует о наличии в пласте выбросоопасной структуры.The results of the data obtained put 5 on the graph (Fig. 2), which set the zone of low temperatures, which indicates the presence in the reservoir of outburst hazardous structure.

На участке с наименьшим значением температур (фиг. 2) бурят шпуры под разнымиIn the area with the lowest temperature value (Fig. 2), drill holes under different

10 углами наклона к поверхности забоя (фиг. 3). 10 angles of inclination to the surface of the face (Fig. 3).

В каждом шпуре через 1 м замеряют температуру соляных пород. Область, ограниченная точками с наименьшими температурами, представляет собой ядро выбро15 соопасной структуры.In each hole, the temperature of the salt rocks is measured after 1 m. The region bounded by the points with the lowest temperatures is the core of the selected 15 hazardous structure.

При разности температур в шпуре, пробуренном в геологически выдержанной зоне и геологически нарушенной зоне, более 1,7°С ядро выбросоопасной структуры соляных пород считают опасными по внезап20 ным выбросам.With a temperature difference in a borehole drilled in a geologically aged zone and a geologically disturbed zone, more than 1.7 ° C, the core of the outburst structure of salt rocks is considered dangerous due to sudden emissions.
