Embodiment 1

[0035] The mining rock mass is layered sandstone, and the static blasting energy-gathering device 3 and its method of use are a static blasting energy-gathering device and its blasting method disclosed in Chinese Patent Application No. 201510171972.1. The cracking range of the static blasting energy-gathering device 3 is 0.5 meters, and the rock formation is determined to be horizontal through the survey of the rock mass, and the thickness of the rock formation is about 0.2 meters.

[0036] Such as Figure 1-4 Shown, a kind of layered rock mass quarrying method based on static splitting, this method comprises the following steps:

[0037] Step 1: Determine the size of the stones to be collected as L 石 = 1 meter, W 石 = 1 meter, H 石 = 1 meter, available rock mass 1 area L 岩 = 5 meters, W 岩 = 5 meters;

[0038] Step 2: Calculate the number of layers that can be collected on the rock mass 1 that can be mined = the width W of the rock mass that can be mined 岩 / Width of stone...

Embodiment 2

[0056] The rock mass to be mined is mica schist, and the static blasting energy gathering device 3 used and its method of use are a static blasting energy gathering device and its blasting method disclosed in Chinese Patent Application No. 201510171972.1. The cracking range of the blasting energy-gathering device 3 is 0.4 meters. It is determined through the survey of the rock mass that the bedding of the rock mass is about 30 degrees, and the thickness of the rock layer is about 0.1 meter.

[0057] Such as Figure 5-7 Shown, a kind of layered rock mass quarrying method based on static splitting, this method comprises the following steps:

[0058] Step 1: Determine the size of the stones to be collected as L 石 = 2 meters, W 石 = 1 meter, H 石 = 1 meter, available rock mass 1 area L 岩 = 8 meters, W 岩 = 8 meters;

[0059] Step 2: Calculate the number of layers that can be collected on the rock mass 1 that can be mined = the width W of the rock mass that can be mined 岩 / Widt...

Abstract

A stratified rock mass quarrying method based on static splitting includes steps: step 1, determining the size of a required stone; step 2, excavating a free face of a rock mass; step 3, determining an inclination angle a of a stratum surface; step 4, determining insertion point number and positions of static blasting energy gathering devices on the rock mass; step 5, performing primary splitting, namely a first-stratum splitting quarrying; step 6, taking the static blasting energy gathering devices out of each hole; step 7, performing primary splitting, namely multi-stratum splitting quarrying; step 8, calculating; step 9, performing secondary splitting quarrying to obtain the stone in the specific size.By the stratified rock mass quarrying method based on static splitting has the advantages that the problem against safety in quarrying can be solved, the required stone is obtained by static splitting of rocks according to stratification features of the rocks, and accordingly quarrying efficiency is greatly improved, other rock stratums are less affected, stability of quarried rocks is relatively less affected, and high safety is achieved.

Description

technical field [0001] The invention relates to the field of quarrying, in particular to a layered rock mass quarrying method based on static splitting. Background technique [0002] With the development of my country's construction industry and the improvement of living environment requirements, people have higher and higher requirements for the efficiency and safety of mountain quarrying. The usual mountain quarrying is through explosive blasting, which cannot effectively and accurately control the mining range and mining depth, and is more likely to damage the rock structure, which has a greater impact on the stability of the rock mass and is not conducive to safe quarrying. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a layered rock quarrying method based on static splitting, which can solve the problem that is not conducive to safe quarrying, and use the bedding characteristics of the rock to statically s...
