(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.
