Abstract

Изобретение относитс  к горному делу и позвол ет уменьшить фильтрацию поверхностных вод в горные выработки до допустимой величины через гидравлически св занные с руслом реки проницаемые породы. Перед разработкой полезного ископаемого 1 в проницаемых порода определ ют нижнюю границу проницаемой зоны. В границах русла реки 6 и за их пределами определ ют положение расчетных границ зоны вли ни  от подработки 7. Затем отвод т русло реки за пределы границ русла реки и формируют временный водоток 10 речного потока. В границах русла реки настилают слой 8 слабопроницаемого материала. Вдоль расчетных границ зоны вли ни  от подработки русла реки от внешней поверхности сло  слабопроницаемого материала до нижней границы проницаемой зоны возвод т гидроизолирующий экран 9, 11 и 12. Причем его возведение ведут на расчетную длину за пределы русла реки и временного потока. После возведени  гидроизолирующего экрана, подработки сло  и завершени  периода оседани  земной поверхности временный водоток речного потока перекрывают и перепускают его поверх слабопроницаемого сло  в границах русла реки. 5 ил.The invention relates to mining and allows reducing the filtration of surface water into mine workings to an acceptable value through permeable rocks which are hydraulically connected to the river bed. Prior to the development of mineral 1 in permeable rock, the lower boundary of the permeable zone is determined. Within the borders of the river bed 6 and beyond their limits, they determine the position of the calculated boundaries of the zone affected by part-time work 7. Then they divert the river bed beyond the borders of the river bed and form a temporary watercourse 10 of the river flow. Within the boundaries of the river bed a layer of 8 low-permeable material is laid. A waterproofing screen 9, 11 and 12 is erected along the calculated boundaries of the zone from the riverbed from the outer surface of the layer of low-permeable material to the lower boundary of the permeable zone. Moreover, its construction is carried out over the estimated length beyond the riverbed and temporary flow. After the erection of the waterproofing screen, the undermining of the layer and the end of the subsidence period of the earth's surface, the temporary flow of the river flow is blocked and overflowed over the low-permeable layer within the river bed. 5 il.
