CLAIMS:

1. An apparatus, comprising means configured for performing:

- receiving mine operations data from a set of data sources in a mine, the mine operations data comprising sensor data,

- processing the mine operations data to detect a set of events meeting at least one operator attention triggering condition,

- mapping the set of events to a mine model on the basis of location information associated with the events in the set of events,

- determining an affected location area of the set of events mapped to the mine model,

- generating, on the basis of the set of events and the affected location area, an operator attention indicator dependent on density of events in the affected location area, and

- controlling display of the operator attention indicator for the set of events in the affected location area in the mine model to an operator to adjust operation of one or more mine operations devices.

2. The apparatus of claim 1, wherein the means are further configured for performing:

- processing at least some events in the set of events to define at least one associated operator guidance element to adjust the operation of the one or more mine operations devices, and

- controlling display of the at least one associated operator guidance element for the affected location area.

3. The apparatus of claim 1 or 2, wherein the means are further configured for performing:

- causing display of at least one operator guidance element associated with at least some of the events in the set of events in response to detecting an operator input for the affected location area or at least one event associated with the one or more mine operations devices.

4. The apparatus of any preceding claim, wherein the means are further configured for performing:

- processing at least some events in the set of events by a corrective action module to detect at least one corrective action to address at least some of events in the set of events,

- determining one or more mine operations devices and one or more control commands associated with the corrective action, and

- causing transmission of control signals associated with the one or more control commands to the determined one or more mine operations devices in response to detecting an imperative condition for automatic control, or

- generating an operator guidance element indicative of the determined one or more mine operations devices and the one or more control commands.

5. The apparatus of any preceding claim, wherein the means are further configured for performing:

- processing at least some events in the set of events to determine if at least one area alarm condition is met, and

- in response to detecting that the at least one area alarm condition is met, causing the area alarm and/or a safety control action associated with at least the affected area.

6. The apparatus of any preceding claim, wherein the mine operations data comprises sensor data from mobile work machines, and the means are further configured for performing:

- detecting locations of mobile work machines,

- mapping the locations of mobile work machines to the mine model,

- displaying mobile work machine indicators in the mine model on the basis of the mapped locations,

- receiving operator input for controlling operations of at least some of the mobile work machines after displaying the mobile work machine indicators and the operator attention indicator, and

- causing one or more control signals for the at least some of the mobile work machines on the basis of the operator input.

7. The apparatus of any preceding claim, wherein the means are further configured for performing:

- mapping one or more events of the set of events to a location of a mobile work machine on the basis of work machine identification information received with mine operations data associated with the one or more events.

8. The apparatus of any preceding claim, wherein the means are further configured for performing:

- defining at least one visualization parameter for the operator attention indicator in the affected location area on the basis of density of the set of data events and/or a set of parameter values of the set of events in the affected location area, and

- controlling display of the operator attention indicator on the basis of the defined at least one visualization parameter in a production status display based on the mine model.

9. The apparatus of any preceding claim, wherein the means are further configured for performing:

- controlling coloring of a model point on the basis of a first magnitude value within a first radius from a location of an event in the set of events and on the basis of a second magnitude value at a second radius from the location of the event, wherein the second radius is larger than the first radius and the first magnitude value is larger than the second magnitude value, and coloring is not applied for indicating operator attention in the affected location area outside the second radius.

10. The apparatus of any preceding claim, wherein the mine model comprises three- dimensional point cloud data for three-dimensional representation of an underground mine, and the operator attention indicator covers at least a portion of three-dimensional representation of tunnel portion associated with the affected area.

11. An underground monitoring system, comprising one or more data processing devices, one or more user interface devices, one or more data storage devices and one or more communications devices, wherein the system comprises the apparatus according to any one of claims 1 to 10.

12. A method comprising:

- receiving mine operations data from a set of data sources in a mine, the mine operations data comprising sensor data,

- processing the mine operations data to detect a set of events meeting at least one operator attention triggering condition,

- mapping the set of events to a mine model on the basis of location information associated with the events in the set of events,

- determining an affected location area of the set of events mapped to the mine model,

- generating, on the basis of the set of events and the affected location area, an operator attention indicator dependent on density of events in the affected location area, and

- controlling display of the operator attention indicator for the set of events in the affected location area in the mine model to an operator to adjust operation of one or more mine operations devices.

13. The method of claim 12, further comprising:

- processing at least some events in the set of events to detect at least one corrective action to address at least some of events in the set of events,

- determining one or more mine operations devices and one or more control commands associated with the corrective action, and

- causing transmission of control signals associated with the one or more control commands to the determined one or more mine operations devices in response to detecting an imperative condition for automatic control, or

- generating an operator guidance element indicative of the determined one or more mine operations devices and the one or more control commands.

14. A computer program comprising code for, when executed in a data processing apparatus, to cause the apparatus for performing:

- receiving mine operations data from a set of data sources in a mine, the mine operations data comprising sensor data,
