METHOD FOR PREVENTION OF CAVE FORMATION OVER OLD MINE WORKINGS |
| 摘要 |
A method for prevention of cave formation over old mine workings includes drilling a group of wells in under-worked compacted rock massif that lays over the old mine workings, not coming to the roofs of those, and pumping in binding agents to the wells under pressure, beginning from the lower horizons to the upper ones. First SKAT binding agent is injected to carbon rocks, and then 20 % solution of aluminum sulphate is injected to loamy running deposits. |
