Documentation of blasting
(I).
Routing Essentials blasting
Technological process of blasting shall contain, in particular, the definition of
explosives and equipment authorised for use in the workplace, the establishment of
blasting technology and constraints for blast way
protection of the surrounding area from the effects of a blast, the required number of workers, including
střelmistrů, the situation of the place of the blast and its immediate surrounding area with
the definition of the handling of space and safety circuit and method
their evacuation and closure of, the means of promulgating warning
signals and the emergency signal and the method of their promulgation, waiting time,
principles determining the hiding places of the workers and of the place of swing, the layout and size of the
load, method of priming and tolerance between the measured and calculated
the resistance of the roznětného circuit, security, machinery and electrical
the affected device, trhacími way, seal measures
When you selhávce including the method of liquidation, authority and responsibility
workers involved in the blasting works, conditions for any
cartridge explosives Division, starting when one is in the bore hole roznětná
booster, charging the roznětných cartridge, use multiple
roznětných cartridge fitted, adjust roznětné cartridges several
detonators.
Additionally, you must edit the technological process of blasting conditions in
cases where so expressly provides for the Ordinance.
II.
Technical project blast
Technical project the blast must have the following sections:
and) a technical report on the grounds of the project solution, the calculation of the
size of load, including values of partial coefficients, calculation of security
the coping and schema management, technological procedure roznětného blasting
work, the solution side effects side effects of blasting on
the area, a breakdown of the measures to ensure safety in the blasting and with
any other necessary information on the nature of the blast,
(b)) the drafting section in compliance with the nature of the blast, including the situation
territory marking points and plotting the hard of the safety circuit
designating Habitat patrols. The method of representation and scale drawings must
allow to obtain sufficiently precise data for the calculation of the load,
laying out their positions for the preparatory work and for the eventual disposal of
selhávky,
(c)) in underground workplaces also
1. project of ventilation, which shall in particular include the calculation of the amount of
of explosion combustion products harmful to health, and measures the time required to
a decrease in their concentration on the limit laid down by the competent
safety and hygiene rules, where appropriate, the technical measures
against penetration of explosion combustion products into the větrního stream, vtažného #
where did swing and its protection against cracking, and method of controlling
the atmosphere for the preparation of blasting and after them,
2. the proof by calculation, as appropriate, the necessary preliminary tests, that
seismic effects blasting shall not affect important underground works, including
the place where it sets off and surface objects to an extent which would endanger
their safe operation and other protected interests.
