Embodiment Construction

[0038] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] This embodiment provides a Figure 5 The lithology identification method based on the mining drilling rig is shown, including:

[0040] Step 1. Establish a comprehensive geological profile in the mining area characterized by rock hardness and a stratum sequence profile of the drilling rig, and couple to obtain the geological-drilling rig data profile;

[0041] The comprehensive geological profile of the mining area characterized by rock hardness is established as follows:

[0042] Step 1.1. According to the geological exploration data of the mining area, establish a comprehensive geological profile of the mining area involved in all piercing and blasting operations in the open-pit mine: collect rock samples, and conduct laboratory testing of rock physical and mechanical parameters in order to understand and control the d...

Abstract

The invention provides a mine drill-based lithology identification method. The method comprises the following steps of: establishing a mine district comprehensive geological section and a drill rock stratum sequence section, which take rock hardness as features, and coupling the two sections to obtain a geological-drill data section; fitting a multiple regression model by utilizing rock hardness,recorded by the drill rock stratum sequence section, of each rock stratum and a corresponding drill working parameter; in a drilling and blasting operation process, adjusting a set drill drilling working parameter in real time according to the geological-drill data section, and identifying rock hardness by utilizing a rock hardness identification model; and determining an explosive charge to be filled by each rock stratum according to the rock hardness, a stratum position, an embedding depth and a thickness of each rock stratum in the drilling, forming an explosive charge filling decision-making command and issuing the explosive charge filling decision-making command to an operation site to carry out explosive filling. According to the method, lithology hardness is grasped to serve features, filled explosive charges and positions are targeted, and secondary rock breaking is decreased while moderate rock lumpiness is obtained, so that shipping arrangement is convenient.

Description

technical field [0001] The invention relates to the technical field of piercing and blasting in open-pit mines, in particular to a lithology identification method based on a mining drilling rig. Background technique [0002] Engineering drilling rigs are generally divided into three categories: one is the geological exploration category, which is mainly used for drilling underground core rock samples and physical detection; the other is geotechnical engineering drilling, which is mainly used for pouring or placing pile foundations; There is also a drilling rig for open pit mines, which is mainly used for perforating, filling explosives and blasting rock ore. [0003] Perforation blasting (referred to as piercing and blasting) is an important process in open-pit mines (including two processes: perforation and blasting), which creates conditions for mining and loading, transportation and soil discharge (referred to as loading, transportation, and discharge). Mines have certai...
