Abstract

The invention discloses a deep well gravity ice conveying and streaming guiding type rapid and controllable ice melting device, which comprises a ground ice making machine, a ground ice conveying device, a gravity ice conveying mechanism, a downhole ice conveying device and a downhole ice melting device. The ground ice conveying device is connected with the ground ice making machine; the gravity ice conveying mechanism comprises a wellhead hopper and a plurality of sections of vertical well ice conveying pipelines, and a buffer rubber spacer is arranged between every two adjacent sections of vertical well ice conveying pipelines; and the downhole ice melting device comprises an ice melting pool, an ice melting pool ice feeding pipe and a water feeding pipe, a plurality of streaming guidingpartition plates are arranged in the ice melting pool at intervals in vertically staggered, arrayed and laid out modes, and the bottom side wall of the ice melting pool is provided with a hole platewater outlet and a water discharging quantity adjusting flashboard. The invention further discloses a deep well gravity ice conveying and streaming guiding type rapid and controllable ice melting method. The violent vibration and damage phenomena, caused by the high well depth and high fall, of a pipeline and a pipeline support in the ice falling process can be relieved well, the heat exchange effect is good, and the sufficient cooling capacity can be provided for deep-mining high-temperature mines.

Description

technical field [0001] The invention belongs to the technical field of mine heat damage prevention and control, and in particular relates to a deep well gravity ice transport and flow-guided rapid and controllable ice-melting device and method. Background technique [0002] With the gradual reduction and depletion of shallow mineral resources, deep mining has become an inevitable trend. At present, mines facing deep mining in my country account for about 90% of the total number of mines in the country. With the gradual increase of mining depth, the problem of high ground temperature has become increasingly prominent, resulting in the deterioration of the operating environment, ventilation and cooling, and a sharp increase in production costs. At the same time, continuous high temperatures have a great impact on human health and work efficiency, and bury major hidden dangers for safe production . Therefore, when deep mines are mined, the problem of heat damage caused by high...
