Method for treating room-pillar type goaf
The invention relates to the technical field of mining area treatment, in particular to a method for treating a room-and-pillar goaf, which comprises the following steps: arranging a water pumping drilling position and a grouting drilling position on the room-and-pillar goaf, the grouting drilling position and the water pumping drilling position corresponding to the goaf space; punching is conducted on the water pumping drilling position and the grouting drilling position correspondingly, so that a water pumping hole and a grouting hole communicating with the goaf space are obtained; hardenable grout is injected into the goaf space through the grouting hole, and meanwhile underground water in the goaf space is pumped out through the water pumping hole; after the grout is hardened, a monitoring drilling position is arranged on the room-pillar type goaf, punching is conducted on the monitoring drilling position, a monitoring hole used for observing the grout filling rate is obtained, and the monitoring hole is communicated with the goaf space. According to the method for treating the room-and-pillar goaf, the stability of the room-and-pillar goaf can be improved, and the situation that the room-and-pillar goaf collapses is avoided.
本发明涉及矿区治理技术领域，具体地，涉及一种治理房柱式采空区的方法，该方法包括：在所述房柱式采空区上布置抽水钻位和注浆钻位，所述注浆钻位和所述抽水钻位与所述采空空间对应；在所述抽水钻位处和所述注浆钻位处分别进行打孔，以得到与所述采空空间连通的抽水孔和注浆孔；通过所述注浆孔向所述采空空间内注入可硬化的浆液，同时，通过所述抽水孔将所述采空空间内的地下水抽出；在所述浆液硬化后，在所述房柱式采空区上布置监测钻位，并在所述监测钻位处进行打孔，得到用于观察所述浆液充满率的监测孔，所述检测孔与所述采空空间连通。本发明的治理房柱式采空区的方法可以提高房柱式采空区的稳定性，避免房柱式采空区出现塌陷的情况。
