Hydraulic static blasting hydraulic tube

Abstract

The invention relates to a hydraulic static blasting hydraulic tube, which is characterized in that: the hydraulic pipe is provided with at least five connection ports, wherein the connection ports comprise connection ports and branch connection ports on two ends of the pipeline; the hydraulic pipe is of a special pipeline which is necessary for the hydraulic static blasting method. The hydraulic static blasting hydraulic tube is suitable for cutting rock or concrete fragile material, is mainly used for mining stone in a hydraulic static blasting method, and is of a special component product for hydraulic static blasting device which is used for mining stone.

Description

technical field [0001] The invention belongs to a stone mining technology and equipment, in particular to a static blasting technology and equipment. Background technique [0002] Static crushing method (static blasting technology) is a new method of breaking (or cutting) rock and concrete developed in recent times, also known as static cracking and static crushing technology. Rather, it is static detonation chemistry. The basic principle and basis are: general rock or concrete are brittle materials, and the compressive strength of brittle materials is high, but the tensile strength is small, and its tensile strength is much smaller than the compressive strength. The tensile strength of rock is 4-10Mpa, and the tensile strength of concrete is about 1.5-3.0Mpa, which is about 1 / 10-1 / 20 of its compressive strength. Usually, the expansion pressure of the static breaker can reach 30-50Mpa. Therefore, a reasonable crushing design (determination of charge amount, hole diameter,...

Problems solved by technology

[0004] It exists, after filling the expansion cracking agent, the rock generally takes 1-3 days to crack, and the efficiency is low; the effect is not good when the temperature is low, and when it is close to 0°C, the expansion cracking agent stops the chemical reaction and cannot be used; the expansion cracking agent As a disposable consumable, the amount of expansion agent is large, wasting resources, and the production cost is high; the generated waste residue pollutes the environment, etc.

[0005] Using keywords to search Chinese patents and authoritative websites and market surveys, one patent related to the static blasting chemical method was found, which was applied by Lin Zongshou of Wuhan University of Technology, and the patent No. Articles and products related to blasting methods
