Abstract [sv]

Examensarbetet genomfördes hos Bergsskolan i Filipstad, i samarbete med Skanska Industrial Solutions AB, region bergmaterial. Uppföljningen begränsades tidsmässigt och omfattade perioden april – juni 2019. Arbetets huvudsyfte var att skapa ett uppföljningssystem som Skanska sedan kunde utveckla till ett ordentligt arbetsredskap inom losshållningen. Systemets fokus riktades mot de viktigaste sprängtekniska parametrarna inom sprängteknik. För skapandet utav uppföljningssystemet användes sprängjournaler från Skanskas bergtäkter i Sverige, samt nödvändig data från SGU:s bergartskarta där bergtäkternas respektive bergarter hämtades från. Systemet skapades i dataprogrammet Excel. Systemet är baserat på bergarten kontra bergtäkten, där salvinformationen är kopplad till respektive bergtäkt. Systemet fungerar på följande vis: 1. Välj den bergart du söker  systemet visar då de bergtäkter som innehar den bergarten. 2. Klicka på den bergtäkt du söker  systemet kopplar dig till täktens salvinformation. 3. Välj salvnummer och fyll sedan i salvinformationen med önskad data. 4. Spara filen  klar! Resultatet visade att målet var uppnåeligt. Ett system där sprängningar följdes upp i de olika bergarterna skapades. Uppföljningssystemet som presenterades är endast en prototyp som för att funka ordentligt för företaget bör byggas vidare i en annan databas (inte Excel).

Abstract [en]

The master thesis was made at Bergsskolan in Filipstad in cooperation with Skanska Industrial Solutions AB. The follow-up was made during the time period of April – June 2019. The main purpose of the thesis was to create a follow-up system that Skanska could use and develop into a real working tool in the future. The focus of the system was aimed at the most important parameters of successful blasting. Skanskas blasting records from the different opencast mines were used to create the follow-up system. SGU: s rock map of Sweden was also used to locate the different rock types in the opencast mines. The system was created in the data program Excel. The system is based on rocks versus mines, were the blasting information is connected to the mines. The follow-up system works like this: 1. Choose the type of rock you are searching for  the system will then show you all the opencast mines that operate in that kind of rock. 2. Click on the mine that you are searching for  the system will take you to that mines blasting information. 3. Choose the burst number and apply all the relevant blasting information in the right boxes. 4. Save the file  done! The result showed that the goal of the thesis was reachable. A follow-up system was created were blasting information in different rocks was shown. The system is only a prototype of how a follow-up system in different rocks can look like. If the company wishes to use the system, then it should be recreated in another data program (not Excel) that specifies on database programming.
