Problems solved by technology

In addition, unrestrained, destructive, and even destructive plundering of resources has resulted in a large waste of stone as a non-renewable resource
As we all know, the price of large blocks of a certain size is double that of small blocks, but the mining methods of domestic enterprises cannot mine large and high-quality blocks, because explosives cannot control the volume of blocks. Cracks also tend to appear inside the stone

Embodiment Construction

[0031] Such as figure 1 As shown, a stone mining process provided in this specific embodiment is mainly used for mining common stones such as marble and granite, and includes the following steps:

[0032] One punch: if figure 2 As shown, on the stone ore body 2 of the mine 1, a row of holes 4 are punched according to the preset position of the pre-splitting block 3, so as to prepare for the subsequent splitting. Pre-split blocks 3 such as figure 2 As shown, the length is C, the width is K, and the height is G; generally speaking, the aspect ratio G / K should be greater than 2, otherwise it is not easy to split and it is not convenient to overturn it later. The spacing between the holes 4 should generally be between 10 and 100 cm, preferably the hole spacing ranges from 10 to 50 cm.

[0033] Punching 4 can use common pneumatic pick, also can use hydraulic rock drilling machine, hydraulic rock drilling jumbo, according to pre-split position, punch a row of holes 4. Pneumati...

Abstract

The invention discloses a stone mining process, which comprises the following steps of: 1, drilling holes for the first time: drilling holes at preset positions of a stone ore body; 2, splitting for the first time: splitting part of the stone ore body from the stone ore body by utilizing the drilled holes to form a large-sized quarry stone; 3, jacking the quarry stone; 4, drilling holes for the second time: drilling holes at preset positions of the quarry stone; 5, splitting for the second time: splitting the large quarry stone into large building stones; 6, chopping: chopping smaller blocks left after the secondary splitting into small-dimension stones; and 7, crushing: crushing much smaller chopped blocks left into gravel and / or stone powder in various specifications. The stone mining process of the technical scheme can greatly improve the yield of high-quality stones, and improve the profits of stone mining enterprises; more importantly, the nonrenewable resources, namely stones can be fully utilized, and the effective utilization rate is near 100 percent.

Description

technical field [0001] The invention relates to the technical field of stone mining, in particular to a stone mining process. Background technique [0002] The history of stone mining can be traced back thousands of years. For example, my country had a stone industry in BC. However, in Hanoi with a long history of thousands of years, the technology of stone mining is relatively primitive and backward. Most of the stone industry is only handcrafted. The way of workshop exists, and this workshop-like production mode handed down from history has continued to this day. [0003] In the era of vigorously developing township enterprises, the laws and regulations of our country allow township enterprises to enter the edge of the ore bodies of state-owned enterprises to mine stone materials, and this kind of mining still continues the small workshop mining method of our country for thousands of years. Driven by interests, many mining companies are eager to convert mineral resources i...
