2.A.5.a Quarrying Mining Other Than Coal

Mining other than coal

Short description
The mining process emits important amounts of particles. Here quarrying and mining of minerals other than coal is subsumed, in particular mining of limestone and building sands.
Information about key source relevance you find within the overview '2.A'.

Method
Activity data
Activity data are determined via summation of figures for various materials like limestone and building sands. Data bases on information on production statistics are available from national statistics. That's why we can assume a common uncertainty of 3%.
Emission factors
The emission factors used for emissions calculation are based on defaults (EMEP/EEA emission inventory guidebook, Version 2009, chapter NFR 2.A.7.a). But because of an update-discussion in 2012 we use here more conservative EF of a discussion paper (see Annex 3).

pollutant Name of Category EF unit Trend
TSP mining other than coal 0.102 kg/t constant
PM10 mining other than coal 0.05 kg/t constant
PM2.5 mining other than coal 0.005 kg/t constant

Recalculations

Recalculation activities were not necessary.

Trends in emissions

Trends in emissions follow the slightly shrinking mining activities.

Salt Production

Short description
Salt production is sub-category of the mining activities in respect of a country specific approach. Currently, a Tier 1 method is used: information on production of salts are multiplied with emission factors for TSP and PM.

Method
Activity data
The data from national statistics includes production of potash and rock salt. Potash salt is dominating, nevertheless gaps of statistics are fulfilled and emissions are modeled like potash salt only.
Emission factors
The emission factors are based on analogy to bulk product handling by an expert judgements from UBA:
Particle-class EF [kg/t salt]
TSP 0.031
PM 10 0.016
PM 2.5 0.003

Recalculation

Recalculation activities were not necessary.
