MAN-MADE RETAINING DAM FOR UNDERGROUND RESERVOIR WITH COAL MINE DISTRIBUTED AROUND, AND DAMMING METHOD OF SAME

Номер: WO2015021782A1
Автор: GU, Dazhao, LI, Quansheng, CHEN, Sushe, CAO, Zhiguo
Принадлежит:

A man-made retaining dam for an underground reservoir with a coal mine distributed around, and a damming method of same. The man-made retaining dam comprises a support layer (10), an anti-seepage layer (20), and a concrete structure layer (30) that are successively formed in an auxiliary tunnel (1) from inside to outside, the concrete structure layer (30) being embedded into a safety coal pillar (2) and/or surrounding rock (3) around the auxiliary tunnel (1). Because the concrete structure layer (30) is embedded into the safety coal pillar (2) and/or the surrounding rock (3) around the auxiliary tunnel (1), the man-made retaining dam is combined to the safety coal pillar (2) to together form a retaining dam for an underground reservoir. Due to multi-layer design, anti-seepage performance and structural strength of the retaining dam can meet the water storage requirements of the underground reservoir.

METHOD FOR PROTECTING/PURIFYING WATER BY RECHARGING IRON-CONTAINING SEWAGE INTO STRATUM DESTROYED BY COAL MINING

Номер: WO2019119933A1
Автор: JU, Jinfeng, LI, Quansheng, XU, Jialin
Принадлежит:

Disclosed is a method for protecting/purifying water by recharging iron-containing sewage into a stratum destroyed by coal mining. According to the method, iron-containing sewage recharging holes and oxygen-containing water/weak alkali water recharging holes are drilled in the ground surface corresponding to the boundary and middle of a mining area, respectively; mining-induced fractures are effectively blocked by means of Fe(OH)3 flocculation sediments generated by the oxidation reaction between iron components in the iron-containing sewage and the oxygen-containing water/weak alkali water. The generated Fe(OH)3 flocculates can gradually precipitate within a certain range near the recharging holes to form an iron active filter membrane, so that a catalyst effect is achieved on the oxidation reaction of iron or ferrous ions, thereby effectively ensuring an iron removal effect. Iron components in a water resource gushing from a low-lying position in a downhole mined-out area are tested; ...

MAN-MADE RETAINING DAM FOR COAL MINE UNDERGROUND RESERVOIR, AND METHOD FOR CONNECTING COAL PILLAR DAM BODY, SURROUNDING ROCK, AND SAME

Номер: WO2015021783A1
Автор: GU, Dazhao, LI, Quansheng, CHEN, Sushe, ZHANG, Kai
Принадлежит:

A man-made retaining dam for a coal mine underground reservoir. A man-made retaining dam (30) is embedded into a coal pillar dam body (2) and surrounding rock (3) around an auxiliary tunnel (1), a cross section of the man-made retaining dam (30) is an arc, and a concave surface of the arc man-made retaining dam (30) faces an underground reservoir. Also disclosed is a method for connecting a coal pillar dam body, surrounding rock, and a man-made retaining dam for a coal mine underground reservoir. The retaining dam improves anti-sliding performance of a man-made retaining dam, and can effectively absorb the impact on the dam body when the water pressure suddenly increases.

WATER RETENTION METHOD FOR PROMOTING SELF-REPAIRING OF MINING-INDUCED FRACTURE BY CHEMICALLY SOFTENING CARBONATE ROCK

Номер: WO2019214031A1
Автор: JU, Jinfeng, LI, Quansheng, XU, Jialin, MAO, Xiaosong
Принадлежит:

Disclosed is a water retention method for promoting the self-repairing of a mining-induced fracture by chemically softening a carbonate rock, the method comprising confirming the information of a distribution range in which an overlaying rock water-conducting fracture zone is in communication with a water-bearing stratum (1) within a mining area, and the information of a rock stratum rich in carbonate rock minerals; in the mining area, drilling a hole from the surface to a target rock stratum (2), which is rich in carbonate rock minerals, within the range of the water-conducting fracture zones, and below the water-bearing stratum (1); and injecting a softening agent into fractures of the target rock stratum (2) through the drill-hole, such that the softening agent is fully reacted with the carbonate rock minerals in the target rock stratum (2) so as to soften the carbonate rock, which induces the gradual closing of tensile fractures in a rock mass under the action of a mining-induced formation ...

Folding type long-distance telescopic targeted filling hydraulic support and end part filling mining method

Номер: CN116044472A
Автор: LI QUANSHENG, ZHAO BOZHI, ZHU WEIBING, GUO CHUNLEI, LI TIANYU
Принадлежит:

The foldable long-distance telescopic targeted filling hydraulic support comprises a base, a hydraulic stand column, a top beam, a filling supporting plate and a suspension arm, the rear end of the top beam is hinged to the filling supporting plate, the suspension arm is fixed to the lower portion of the filling supporting plate, and the suspension arm comprises a rotating mechanism, a lifting mechanism, a folding mechanism and a filling mechanism which are sequentially connected; during use, the hydraulic filling support is arranged at an interval with conventional hydraulic pressure, and the defect that the cost is high due to the fact that a traditional filling working face completely adopts filling supports is overcome. Based on the targeted filling hydraulic support, the invention further provides an end filling mining method, filling is only carried out on the end of the goaf, a pelvic floor type goaf is formed, the problems that the opening degree of longitudinal fractures of mining ...
