Embodiment Construction

[0034] The technical solutions and beneficial effects of the present invention will be clearer and more definite by further describing the specific embodiments of the present invention in conjunction with the accompanying drawings.

[0035] Such as figure 1 , figure 2 and image 3 Shown, the present invention comprises limestone mine abandoned pit and following steps:

[0036] Step 1. Determine the weir crest elevation, and determine the weir crest elevation and spillway of the reservoir or pond or pond according to the topography of the abandoned mine pit of the limestone mine and the current topographic survey map.

[0037] Step 2, determine the water storage capacity and the slope step 4, take the lowest point of the abandoned mine pit sag in the limestone mine as the datum line for design and repair, and determine the water storage capacity of the reservoir or pond or pond and the height of the slope step 4 in combination with the elevation of the weir crest. Width and...

Abstract

The present invention firstly determines the weir crest elevation, spillway, water storage capacity and the height, width and number of steps of the side slope in the abandoned mine pit of the limestone mine, then trims the steps of the side slope step by step from top to bottom, and then abandons the limestone mine. The side and bottom of the pit are blasted to form a foundation pit, then the karst hole is detected and sealed, the inner wall of the foundation pit is closed, and finally the slope steps are arranged with vegetation, thus providing a kind of The reclamation method of transforming the abandoned pits of limestone mines into reservoirs, ponds, and ponds provides a feasible solution for the reuse of abandoned pits in limestone mines. It has the characteristics of ingenious conception, easy implementation, low investment, and high economic value.

Description

technical field [0001] The invention relates to a reclamation method for transforming abandoned pits of limestone mines into reservoirs, ponds and ponds, which is mainly used for transforming abandoned pits of limestone mines into reservoirs, ponds and ponds for water storage. Background technique [0002] At present, there are tens of thousands of various abandoned mine pits formed due to the closure of limestone mines across the country. The area of ​​abandoned limestone mines in various provinces and cities is calculated in units of 10,000 mu. According to the law, reclamation must be carried out when the mine is closed, but due to various technical reasons, the effect of reclamation is not ideal. How to restore 100% of the abandoned pits of limestone mines to the ecology before mining is a reclamation problem that needs to be solved urgently. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a reclamation met...
