Salt-field collection operation method

Abstract

The invention discloses an operation method for harvesting salt field, which is characterized in that according to the positions of hydraulic mining ship and wharf, under the control of GPS system, fold and snap accident of the floating pipeline in harvesting process by the movement of anchor ship position is avoided completely, greatly increasing stability of coal mining and reducing maintenace expenditure of equipment.

Description

technical field [0001] The invention relates to a harvesting method, in particular to a saltfield harvesting operation method. Background technique [0002] The Lop Nur area in Xinjiang, my country has abundant reserves of salt mine resources, gold and other resources, especially the extremely rich potassium salt resources. It was further proved in 2002 that the reserves of potassium salt resources reached 500 million tons. According to the calculation of authoritative geological experts, it is fully equipped It has the resource potential to become the largest potash production base in my country. At present, the method adopted for the mining of potassium salt in the Lop Nur area is: to pump the groundwater rich in potassium salt into the salt pool set up in advance on the ground, and the groundwater rich in potassium salt is exposed to the sun and evaporated in the air, and the potassium salt crystallizes and precipitates in the salt pool The open-air salt bed is formed, an...

Problems solved by technology

[0003] Because the site environment of the salt field is often windy and the wind often produces huge waves, it is also necessary to set an anchor ship to fix the floating pipe. The salt bed is crushed, so it often happens that the straight-line distance between the water harvesting ship and the anchor ship and between the anchor ship and the wharf is greater than the length of the floating pipe with a predetermined length, causing the floating pipe to be broken, or the floating pipe is too bent and the floating pipe is twisted Accidents, thus affecting the normal harvesting operations of water harvesting vessels, resulting in huge maintenance costs and heavy losses
