Blasting System Protective Plate Recess Debris Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blasting systems for boreholes lack adequate safety measures to protect personnel involved in the blasting process, especially when conducted near the surface, as they do not effectively contain the explosive force and debris, leading to risks for people and equipment.
Innovation Solution
A blasting method and arrangement that involves a protective plate with a recess over the borehole, where the detonator protrudes into or through the recess, ensuring that explosive force is concentrated underground and debris is contained, reducing the risk of material hitting personnel and improving safety and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional blasting systems are used without protective measures, then the blasting process is simpler to perform, but personnel safety is compromised due to uncontained explosive force and debris
Solution Approach 1:
The blasting system is segmented into distinct functional components: a protective plate with recess to contain debris, a drill module for borehole creation, a blasting module for explosive placement, and an ignition module for detonation. This segmentation allows each component to be optimized for its specific function while maintaining overall system safety and manageability
Solution Approach 2:
The protective plate acts as an intermediary element between the explosive force and the surrounding environment. It contains the explosive energy within the borehole while preventing debris from escaping to the surface, thereby protecting personnel without requiring complex containment structures
2Object-affected harmful factors
If the detonator is positioned to protrude into the recess for safety, then debris containment is improved, but the alignment precision required increases
Solution Approach 1:
The protective plate with the recess is prepared and positioned in advance before the blasting operation. The recess is pre-formed with dimensions that accommodate the detonator, ensuring that when the detonator is inserted, it automatically achieves the correct alignment and protrusion depth into the recess without requiring complex real-time adjustments
Solution Approach 2:
The protective plate features a localized recess with specific dimensional characteristics that match the detonator geometry. This local quality enhancement at the critical interface between the protective plate and detonator ensures proper alignment and debris containment while keeping the rest of the protective plate simple in structure

Function Achieved in This Case
The method significantly reduces the risk of debris hitting personnel and improves the efficiency of the blasting process by concentrating the explosive force underground, allowing for safer and more efficient blasting operations with reduced material escape to the surface.

AI summary
The invention relates to a blasting system which is ignited in a bore hole. The invention relates to a blasting method and a blasting assembly (1) for this purpose. The blasting assembly (1) according to the invention for blasting a blasting capsule (10) introduced into a bore hole (2) is provided with a support (3). The support (3) has at least one protective panel (4) with a recess (5). The support (3) is equipped with a boring module (6) which is suited and designed to introduce a bore hole (2) into the underlying surface (21), a blasting module (7) which is suited and designed to introduce a blasting capsule (10) into a bore hole (2) with a projection (14) over the underlying surface (21), and a detonation module (8) which is suited and designed to detonate a blasting capsule (10) which reaches the recess (5) of the protective panel (4). The vertical projection (14) of the blasting capsule (10) protrudes into the recess (5) of the protective panel (4) and thereby closes the unobstructed passage through the recess (5). By at least partly closing the recess (5), it is ensured that in the event of a blast, particles of the underlying surface (21) cannot pass through the recess (5) and injure persons or damage equipment in the surroundings of the blast or can only pass through the recess to a very limited extent. In this manner, good handling characteristics and a markedly high degree of safety are ensured during the blasting process.
