Mining other than coal

Short description
The mining process emits relevant amounts of particles. Quarrying and mining of minerals other than coal is subsumed, in particular mining of limestone and building sands.
Information about the key source relevance can be found in [[2-a-mineral-industry | 2.A Mineral Industry]].

Method

Activity data
Activity data are determined via summation of figures for various materials like limestone and building sands. Data based on information on production statistics are available from national statistics, therefore a common uncertainty of 3% is assumed.

Emission factors
The emission factors used are the UNECE-Defaults (EMEP/EEA emission inventory guidebook, Version 2013, chapter NFR 2.A.5.a, no changes in 2016 version).

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 a sub-category of the mining activities in respect of the country specific approach used. 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 filled and emissions are modelled as potash salt only.
Emission factors
The emission factors are based on analogy to bulk product handling by an expert judgements from UBA:
pollutant EF [kg/t salt] Trend
TSP 0.031 constant
PM 10 0.016 constant
PM 2.5 0.003 constant

Recalculation

Recalculation activities were not necessary.
