Open pit mined-out area through hole plug and through hole plugging method thereof

Abstract

The invention relates to a hole plug, in particular to an open pit mined-out area through hole plug and a through hole plugging method thereof. The upper end of an upper wood wedge (2) is a plane, the lower end of the upper wood wedge (2) is an inclined plane (4), and an iron wire (1) through hole (3) is formed from the center of the upper end plane of the upper wood wedge to the center of the lower end inclined plane; and one end of a main wood wedge (6) is a plane, the other end of the main wood wedge (6) is an inclined plant, and an iron wire through hole is formed from the upper part of the main wood wedge (6) to the lower part of the wood wedge (6), an iron nail (5) is arranged on any side of a through hole in the lower part of the wood wedge (6), and the lower end of the iron wire is fixedly connected with the iron nail and then the iron wire passes through the through hole in the main wood wedge and the through hole in the upper wood wedge. The open pit mined-out area through hole plugging method comprises following steps: pretreating the through hole; measuring hole diameter; making a plug; mounting the plug; filling explosive; and exploding. In the invention, the trees influencing exploitation in during mining area exploitation are fully used, the waste is changed into valuable materials, explosive is saved, explosion cost is saved, and through hole plugging time and labor force are reduced.

Description

【Technical field】 [0001] The invention relates to hole plugging, in particular to an open hole sealing and plugging method for an open-pit mining area converted from an underground mine to an open pit and the hole plugging method. 【Background technique】 [0002] It is well known that goaf treatment is a complex work that must be carried out when underground mining is converted to open-pit mining, and the plugging of through holes is the primary task of goaf treatment. Take the Sandaozhuang mining area of ​​our company as an example: After more than 30 years of unreasonable mining in the Sandaozhuang mining area, especially from the mid-1980s to the late 1990s, this mining area was the peak period of disorderly mining and indiscriminate mining. The mined-out area of ​​, all the mined-out areas have not undergone any treatment and filling. Due to the existence of a large number of goafs, the processing of goafs has become an important part of the daily stripping work since th...

Problems solved by technology

Our company began to contact the empty area in May 1998. Due to lack of experience, it takes a lot of manpower and material resources every time a through hole appears, and a through hole occurs many times, wasting hundreds of kilograms or even thousands of kilograms of explosives and poor plugging. The phenomenon

Sometimes it takes several hours to process a through hole, which brings great difficulties to the blasting construction
