Ground-underground combined exploration and treatment method for mine geological anomalous body

Abstract

The invention discloses a ground-underground combined exploration and treatment method for a mine geological anomalous body. The method comprises the following steps of 1, exploration, wherein the position of the geological anomalous body is determined, that the geological anomalous body is communicated with gray water is determined, and the water burst risk exists, wherein 1.1 mine underground exploration is conducted, 1.2 three-dimensional seismic exploration is conducted, an anomalous area is delineated, and 1.3 ground exploration is conducted mainly by drilling a hole, and a three-opening well body structure is adopted for the drilled hole; and 2, treatment, wherein 2.1 ground treatment is conducted, and 2.2 underground treatment is conducted. According to the ground-underground combined exploration and treatment method for the mine geological anomalous body, directional drilling of the ground and directional long drilling of an underground bottom plate along the layer are combined according to engineering practice, exploration and treatment of the mine geological anomalous body are conducted, the effects that the exploration and treatment time is advanced, the exploration and treatment space range is large, the exploration accuracy is high, the overall elimination effect of water damage hidden danger is good, a water guide fracture channel is effectively blocked, and the treatment effect is obvious are achieved.

Description

technical field [0001] The invention relates to the technical field of mine detection, in particular to a surface-underground joint detection and treatment method for geological anomalies in mines. Background technique [0002] Geological anomalous body is a special geological structure and a special type of hidden karst. It is formed by the collapse of karst rock mass due to water-solubility. It is mainly distributed in northern my country. The complexity of its structure makes water inrush have great potential The predictability and uncontrollability of mining not only directly affect the rapid advancement of mining at the working face, but also relate to the safe production of the mine. [0003] The geological conditions of my country's coal mines are complex and changeable. For coal fields in North China, there is a thick to extremely thick layer of Ordovician limestone under the main coal seam. This layer of limestone is rich in water, has a huge amount of water, and has...

Problems solved by technology

[0003] The geological conditions of my country's coal mines are complex and changeable. For coal fields in North China, there is a thick to extremely thick layer of Ordovician limestone under the main coal seam. This layer of limestone is rich in water, has a huge amount of water, and has a certain pressure When the water head and the coal mining face are advancing, once they communicate with the Ordovician limestone through hydraulic structures such as geological anomalies, serious floor water inrush accidents will occur. Water seepage accidents. In recent years, with the increase of mine excavation depth, the threat of water damage to coal seam floor limestone has become more and more serious. Conventional rotary drilling is difficult to meet the requirements of limestone exploration and treatment.
