Description
The technical field is as follows:
the invention relates to the field of underground reservoirs of abandoned mines, in particular to a diversion air bag dam protection structure of an underground reservoir of a coal mine.
Background art:
large-scale and high-intensity mining of coal mines brings different degrees of disturbance and influence on the natural environment, ecological environment and resource occurrence geological structure environment of a mining area, and when the bearing capacity of the area environment is exceeded, the area balanced environment condition is damaged. The method is characterized in that the structure and integrity of the overlying strata of the roof are damaged due to coal mining, so that the aquifer is changed from a new water circulation mode mainly from the runoff between layers to the vertical runoff, and therefore most of the underground water of the sandstone weak aquifer of the roof and the fourth-system diving aquifer seep (burst) into the mine goaf. Therefore, in western ecological fragile mining areas, underground reservoirs are reasonably constructed to protect and utilize underground water resources, and the method is an important work for sustainable development of coal resources. In order to protect valuable water resources in a mining area, a goaf formed after coal seam mining can be built into a coal mine underground reservoir.
However, the water pressure of the reservoir brings challenges to the water storage capacity of the coal mine underground reservoir and the safety of the reservoir dam body, so that the invention provides the diversion air bag dam protection structure of the coal mine underground reservoir.
The invention content is as follows:
aiming at the problems in the prior art, the invention provides a diversion air bag dam protection structure for a coal mine underground reservoir.
The invention relates to a diversion air bag dam protection structure of a coal mine underground reservoir, which specifically comprises an I-shaped connector, a dam protection air bag, a diversion column, an artificial dam body and an isolation coal column, and is characterized in that:
the artificial dam body is designed into an I-shaped structure, is connected with the surrounding isolation coal pillars, and ensures that the dam body at the inner layer of the reservoir is smooth;
the flow dividing column is built in front of a dam, is wholly drop-shaped and can be divided into a front-end wave-making column and a tail-end tail-flow column, the front-end wave-making column is designed in a spherical shape and is used for reducing wave-making resistance of a water body and dividing the water body, and the tail-end tail-flow column guides flow of the divided water body to divide different water body pressure distribution structures;
the dam protection air bag is fixed between the diversion columns and the dam body, a wave-resisting bag corresponds to the back of each diversion column, the gap between the diversion columns corresponds to the force-unloading bag, the air filled in the dam protection air bag is 60% -80% of the total filling amount, after the high-pressure water body behind the tail flow column impacts the wave-resisting bag, the air escapes to the force-unloading bag, after the water body is in turbulent flow, the force-unloading bag is pressed, and the air flows back to the wave-resisting bag.
Specifically, anchor cables are arranged in the diversion column, the artificial dam body and the isolation coal column for stabilization.
Specifically, the dam protection air bags can be connected in segments or in height.
Specifically, the dam protection air bag can be filled with gas correspondingly according to the construction environment.
